What are the odds of a viable pregnancy with a condom and Mirena IUD?

This is a question about mathematical odds, be it Million to One or what-have-you.

Considering the percent effectiveness of condoms (98% for “perfect use”), and the percent effectiveness of the Mirena IUD (99.9%), also, factoring in that 20% of pregnancies miscarry in the first trimester, and the actual incidence of ectopic pregnancies with IUD use is (3-4%) – what are the odds of a viable pregnancy occurring?

Can signs of pregnancy start to occur within less than a week after intercourse?

Help! A friend of mine was recently involved in sexual activity and is worried she may be pregnant. No more than a day or two after this sexual activity took place she started having splitting headaches, vomiting and experiencing nausea, she noted that these are some traits often accompanied by pregnancy. I have read that signs of pregnancy such as these should not start to occur until at least a week or two after the intercourse, but this information still does not cease the worrying. Is this at all possible? Could she be pregnant? Please help!

How long before a home pregnancy test can test whether you’re pregnant or not does spotting occur?

I’ve noticed spotting, and looked up a little on it and learned one of the reasons behind it could be the earliest sign of pregnancy. When I took my pregnancy test, it tested negative, and I’m wondering if you start spotting before a home pregnancy can test correctly.

What stage of pregnancy is smoking and drinking the most damaging?

Would it be more dangerous to do these things at the beginning or the end of a pregnancy? I know that fetal alcohol syndrome for example is more damaging during certain months of pregnancy but I do not know which ones.

This is pure curiosity as a biology major.

How long into pregnancy will a home test show a positive answer?

I haven’t had a period for almost two months now. So last week i took two pregnancy tests. One came up negative, but the other one showed a positive result, but was invalid because the line in the second window (that shows up to show that the test worked) never showed up. There is a good possibility im pregnant, but I’m not sure and honestly don’t want to believe I am. How long should it take for a home pregnancy test to say positive?

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.

What were your pregnancy symptoms and how soon did they start?

Hello,

I wanted to hear some of your stories regarding how soon you experienced your first pregnancy symptoms. I did not experience much with my first child other than having to pee often. I actually did a pregnancy test 3 days before my AF was due because I couln’t believe how often I had gotten up to pee during the night. What about you? How soon were your symptons and what were they? I still have 1 week left before I can test for pregnancy…

Thanks for sharing!
