How early in Pregnancy do these get bigger?

The bumps in the areola area. The Montgomery’s glands? How soon in pregnancy to they begin to get larger. I’ve noticed mine are a bit more noticeable. Not much bigger or anything, but more noticeable. I might have conceived this cycle, my period is a day late, haven’t taken a test yet. My breasts have been sore for almost 2 weeks, I’ve been more tired, bloated for 2 weeks, and now I notice the Montgomery’s glands. Is this an early sign of pregnancy? Thanks.

How soon in pregnancy should nipples start leaking clear liquid?

I am 14 weeks along. My breasts are sore. I massage them for comfort. A few days ago, when I was doing so, a clear liquid began seeping from 4 or 5 what seemed like holes in my nipple. And any time I squeeze my breast it continues. I have yet to have an ultrasound. My doctor won’t do one before 18 weeks. Is it possible that I’m further along than she thinks or is this common in early pregnancy?

Early Pregnancy Diagnosis in Ruminants

PREGNANCY DIAGNOSIS IN ruminants

1 Introduction

Rectal palptation in small ruminants is of little value due to the size of the pelvis. (Wani, 1981). The caudal artery monitoring, bloatment, non-return to oestrus, udder development and other tests tried have had little success, (Wani & Sahni,1980). The more recent interest in early pregnancy 3. diagnosis of small ruminants is of academic and economic importance (Mellado,2003). A highly valued zygote or embryo when transferred to a less valued surrogate mother (recipient) needs to be closely monitored and the early detection of conception helps in repeated use of baren females. Proper management of pregnant animals also prevents embryonic losses. The method applied should be safe to both offspring and dam and needs to be cheap and easily applied. A review of various methods and techniques used for early pregnancy diagnosis in small ruminants. (sheep and goats) is presented.

.2 Early Signs of Pregnancy

2.1. Maintenance of a functional corpus luteum

It was evident that conception prolongs the life of the CL and prolongation and maintenance of a functional CL is triggered by the developing conceptus. These signals ensure the maintenance of the structural integrity of the CL. Corpus luteum produces progesterone, which maintains the uterine endometrium in a state permitting embryonic development, implantation and foetal-placental development (wani,1984b) . The formation and regression of the corpus luteum (CL) in Muzzaffarinagri ewes and Jamunapari goats was monitored at 3 days intervals for an entire oestruous cycle. Laparotomy and laparoscopic methods were used in these experiments.

The Endometrium undergoes tissue remodeling. This change in Extra cellular Matrix (ECM ) components is needed for successful implantation. Cytokinens 8,18 and 19 have been detected in the caprine endometrium during early pregnancy using immunofluorescence. Thus the presence of these cytokinen at approximately day 15 post conception is indicative of pregnancy in goats.

The implantation process in goats starts around day 18 post mating. During this phase intense type I collagen staining was detected throughout the uterine caruncular and intracaruncular stroma. For embryonic trophoblastic adhesions with endometrium, local control of protease activity is suggested. (Guillomot, 1999).

The earliest signs of pregnancy is the non-regression of the cyclic CL, which can be observed by the following methods:

i. Laparoscopy and Laparotomy approximately day 18-25 post mating. (Wani, 1982, 1988, 1984b,Wani & Buchoo, 1990, Wani & Buchoo, 1993, Cuellar et al, 1990, Wani et al, 2003).

ii. Serum Progesterone values higher than 1 ng/ml e.g 2 to 3 ng/ml. (Wani, 1989; Shreif, 1997, Boscas et al, 2003, Al-Merestani et al, 1999, Zarkawiet et al, 1999). Diagnosis of Pregnancy accurately (100%) predicted on the basis of serum progesterone P4 values around 17-19 days post mating .

iii. Pregnancy associated ovine glycoproteins recorded approximately post mating indicate pregnancy in sheep. (Karen et al, 2003; Verberckmoes, et al, 2004) or secretion of 17 & 22-24 K Da proteins on day 17 post mating in the caprine conceptus. (Guillomot et al, 1998).

iv. Non-return to oestrus (Mellado, 2003)

Some of the other early pregnancy signs detected by various methods are set out in Table 1.

3 Non-rejection of early conceptus

Progesterone maintains the uterine endometrium in a state which allows for embryonic development, implantation and foetal placental development. Details of foetomaternal relationships have been described (Mufti, 1997, Mufti et al, 2000)and are shown illustrated in Fig 1to 5. The presence of an early conceptus prolongs the life of corpus- luteum. These pregnancy signals are secreted as proteins. (Heap et al, 1990). Some of these proteins have been identified as ovine Trophablast protein I (OTP-1) in sheep which prevents the release of PGF2 alpha and thus helps in the maintenance of the corpus luteum. In cyclic ewes (non-pregnant) PGF2 alpha pulses are released in response to oxytocin with receptors being in the endometrium. The earliest signal of pregnancy is detected by a marked reduction in the endometrial oxytocin receptor numbers. The OTP-1 may inhibit synthesis of endometrial receptors for oestrogen and oxytocin. This possibly prevents luteolysis and maintains the dominance of theuterus by progesterone which is pre-requisite for the establishment and maintenance of pregnancy. (Bretzlaft and Romano, 2001; Wani, 1996; Ala cam et al, 1988).

The expression of progesterone receptors (PR) in the caprine uterus markedly increases during the peri-implantation period and estrogen –(ER) receptors do not increase in relation to PR, thus signaling the non-rejection of the early conceptus. (Flores et al, 2001). Progesterone in milk too can be found during early fertilization and conception (Cough et al, 1989).

Caprine H-type I antigen expression is unregulated during peri-implantation and progesterone P4 level stimulate it. It may be a useful marker to signal uterine preparations for receiving and retaining pregnancy in goats. (Powell et al, 2000). The caprine pregnancy related glycoprotein (Ca PAG) may help the conceptus to develop and is found around 18-19 day post mating . (Garbayo et al 2000). Endometrial tissue the undergoes remodeling to retain the conceptus in gravid small ruminant females. (Guillomot, 1999)

The dephosphorylated state of caprine uterine myocin in early pregnancy may help the conceptus to grow. Changes in the expression of native myocin, myosin heavy chains (MHCS) and myosin light chains (MLCS) were observed. (Kumar and Katoch, 1997).

For the development of the blastocyst, a proper uterine environment is essential. Besides the maintenance of the corpus luteum, production and availability of progesterone, the non-rejection of conceptus (blastocyst) is another critical feature of this period. The embryo produces interferons (embryo-IFN). This embryo IFN is homologous with – interfersons ( ? –IFN) and Ovine Trophoblast Interferons (OTI) of early pregnancy.

Purified OTP and recombinant OTP (r-oTP) produced in yeast exhibit antiviral activity and these r-OTP and OTP inhibit the release of endometrial PGF2 ? . This helps in the non-regression of the CL and indirectly maintains the early conceptus. Intra uterine r-OTP administered at a dose of 340 µg/ day for a week maintained the C.L in cyclic ewes for a month or so of . The inter- oestruos interval in 80% of the ewes was about a month or more. This dose r-OTP was as a effective as 14-16 day old conceptus. OTP was found to be immunosuppressive in several in-vitro and in-vivo assays. An assay on phytohaemagglutinin A revealed both OTP and r-OTP to be immunosuppressive. This was further verified by the inhibitory activity of r-OTP in Graft Versus Host Reaction. (GVH assays). Trophoblast interferons play a strategic role in the prevention of early pregnancy loss as it inhibits CD + blastogenesis. The role of CD + cells and as helper T lymphocytes and delayed+ Type hyper sensitivity mediators (DTHS) would explain this immuno- suppressive rate of OTP. (ILeri et al, 1996; Karen et al, 2003; Wani, 1996).

3.4 Oestrogen: – Pregesterone ratio (E:P ratio)

The role of oxytocin in inducing uterine PGF2 alpha was discussed earlier. However, the release of PGF2 under the action of oxytocin depends on or is controlled by progesterone and oestradiol. It was further indicated that ewes with a high E:P ratio may generate stronger luteolytic signals. It was demonstrated that low progesterone and high oestradiol combination record the largest and sustained increase in PGF2 alpha following oxytocin injection. Trophoblast interferons act locally to suppress the uterine oxytocin receptors in sheep.(Karen et al, 2003 ).

5 Maternal recognition of pregnancy

The maternal recognition of pregnancy in sheep and cattle is centered around the production by the trophoblast of type I x interferon (tINF). This tIFN then suppresses uterine oxytocin receptor concentrations (OTr). The oxytocin receptor (OTr) occupancy is associated with oxytocin induced PGF2 alpha release. OTr inhibition may represent the principal antiluteolytic mechanism of tIFN and secretion of the conceptus secretory proteins or bovine recombinant IFN to the uterus reduces OTr. Concentrations in intact and ovarectionized steroid treated ewes . A relationship between the conceptus secretory proteins and the metabolic products and those in the peripheral blood of the dam exists. ( Mufti; 1996; Mufti et al, 2000). There are conflicting reports making the action of oestradiol on oxytocin receptor concentration. (Powell et al, 2000). Trophoblastic cells contain interferon on day 14-17 after mating. During maternal recognition of pregnancy goat interferon was detected on day 18 post mating, its absence signifies pregnancy maintenance has been taken over by the corpus luteum. Thus a very thin line exists between maternal recognition of pregnancy and its maintenance or sustenance by the CL. (Gillomot et al, 1998).

6 The Reliability Pregnancy tests

Various methods used for correctly predicting pregnancy in sheep and goats during gestation have been summarized in Table 2. The accuracy varies from 70 to100% with different ultrasonic equipment. Different models as well as principles involved have been extensively reviewed (Wani, 1991; Wani et al,1998) and other methods of pregnancy detection during this stage e.g serum progesterone determination, vaginal cytology, laparotomy, estrone sulphate are summarized (Table-2). Various techniques were also evaluated in assessing mid-gestation. The various pregnancy signs as quoted by

various researchers using ultrasonography are summarized in Table 3. Of late certain anatomical features in the live, developing conceptus in vivo have been reported. This is reviewed and a summary is presented (Table 4). Various live foetal measurements like Biparietal diameter, Amniotic vesicle diameter, foetal radius and Tibia lengths are reviewed and shown (Table 5). Various pregnancy related images, histological sections and morphology of endometeruim have recently be published (Wani et al 2007, 2006 abc) where images are presented 6-15

Pregnant Period – 5 Signs of Pregnancy Before a Missed Period

Pregnant Period Your body is a delicate, yet sturdy cluster of parts, authorities and technology, outstandingly when signs of pregnancy before missed time period is concerned. It is very exact in how it reports abnormalities to your brain. Unfortunately, your brain also houses the emotional controls, so sometimes these types of monumental signs become lost, ignored or get “short circuited” when properties get to the brain. And the result? Pregnant Period

You don’t recognize the fact that you’re pregnant! Just in case the early signs of pregnancy before missed period aren’t making the trip to your consciousness, here are five of the most important (and most often ignored) signs. Fatigue I definitely understand how a woman in this day and age can become exhausted and fatigued – without being pregnant. Working 10 – 12 hours a day at a challenging career, then heading home to care for the husband, your home and maybe even a child or two, it’s quite easy to become tired. Pregnant Period

But, I’m talking fatigue here – you’re so tired that you can barely keep your eyes open! I’m sure you’ve experienced tiredness before, but few (those who have not ever been pregnant) have experienced fatigue. No matter how much sleep you get, it’s never enough. You seem to walk around in a trance, like a zombie with your eyes half open and feeling dull-witted. This fatigue is your body’s way of telling you “Hey – slow down, I’m living for two! And, believe it or not, it’s one of the most-missed early signs of pregnancy.

Constipation Now, this sign is just plain irritating, but it’s definitely a great sign, but one that’s frequently missed. No one is sure exactly constipation is one of the 5 Signs of Pregnancy Before Missed Period, but it happens to at least half of all women who become pregnant. Stress and a low fiber diet may contribute to constipation, but it’s easily remedied with relaxation and some fiber added to the diet.

Breast Tenderness and Nipple Enlargement Now, this one should be no surprise to no one – when expecting, your breasts are turning into food factories for the new life inside your body. Your body knows what’s best, and babies who breastfeed realize tremendous benefits from more complete nutrition, to improved disease resistance to a stronger bond between mother and child. Pregnant Period

Your breasts play a supremely important role as life support for your little one that it’s no wonder they undergo major reconstruction during pregnancy. This should be one of the best clues you’ll get about the new life forming inside you. Start raising a family! Get Pregnant Today by getting Pregnant Period ebook now!

A closer look at abortion and Florida’s proposed law
Gov. Charlie Crist soon will have to decide whether to veto House Bill 1143, which requires a woman seeking an abortion in early pregnancy to view an ultrasound and hear a description of the embryo. The measure, pushed through in the final hours of the legislative session, also would make women pay for their ultrasound, which could add $100 to $300 to the $400 typically paid in the United States …

How early in a pregnancy do your boobs start to hurt with little touch or pressure?

I think I’m pregnant and I’m not sure. But when my boobs are lighly tapped or touch, they hurt. It’s only been about 2 weeks since the conception (if im pregnant) so does anyone know if this is pregnancy or my period?

How early in your pregnancy can you start to get morning sickness?

About a week ago, I took a positive pregnancy test. I figure that I’m somewhere between 2 and 3 weeks along, but I haven’t made it to the doctor yet, so I don’t know for sure. For the past three days I’ve felt extremely nauseous. I thought it was too early to be getting morning sickness, but my friend says it can start pretty early. Have I come down with something or is it really morning sickness?
Thanks.

Pregnant Month – The Twelve Month Pregnancy

Pregnant Month

A ordinary pregnancy lasts nine cycles however you should think about a pregnancy lasting twelve months instead. It is a top notch idea for you to prepare your person mentally and physically for an upcoming pregnancy three cycles prior to trying to conceive. This is especially true for women over the age of 40 trying to have a baby.Pregnant Month

During such time, it may be a desired idea for you to seek out the advice of a medical professional in form for you to get all of your questions answered and for you get a check up to obtain assured there is no condition you may suffer the present will in a damaging way affect the pregnancy. During this time, you will want to focus on two things: a healthy diet and, if you are a smoker, quit smoking. These two things have a huge impact on fertility and pregnancy health.

Lots of leafy greens, lean proteins, and fiber will help your body become healthy and provide the fetus with the proper nutrients, especially folic acid. Sufficient amounts of folic acid helps to prevent certain birth defects like spina bifida. Many of these conditions occur very early in the pregnancy so you will want to be as healthy and nutrient-rich from the start. Consuming a prenatal vitamin is a good way to make sure you are taking the right amounts of nutrients. A medical professional can help recommend one for you. Pregnant Month

Smoking a huge factor in fertility and the pregnancy. Most people are aware that pregnancy and smoking should not go together but do not know why. Smoking poses many risks to a pregnancy including birth defects and a low birth weight. Studies have also shown that it can double your risk of having an ectopic pregnancy.

In short, an ectopic pregnancy is where the embryo attaches itself in the fallopian tube instead of the uterus. This is a life-threatening condition that must be addressed immediately and usually discovered by the eighth week of pregnancy. As was mentioned, research has shown that smoking has been linked to fertility problems in both men and women. Pregnant Month

The journal “Fertility and Sterility” cites a study that shows that the sperm count for smokers were 17 percent lower when compared to nonsmokers. Another study in the same journal notes that once smokers stopped, their sperm count dramatically increased up to 800 percent! Start raising a family!
