Hey lovely VPers! I have a question and I just can't seem to find the right combination of words in order to find an answer via google. I'm usually very strict about always using two forms of contraception, so I've never really had a pregnancy scare. And I think I might just be paranoid.
So the situation: I've been on TriNessa for forever. I had PIV sex on the 6th day of my placebo pack (last Thursday), which was also the third day of my 4-day withdrawal bleeding. My boyfriend was only in me for like 30 seconds max and then pulled out. (My nerves can't handle pulling out, I'm definitely an HBC + condoms girl.) But he came fairly quickly after, so now I'm freaking out thinking he might've gotten some inside me before he pulled out.
Now the kicker is, in my infinite stupidity, I forgot that I didn't have any refills for my HBC and because my doctors office was closed for the next 4 days (it was Thanksgiving weekend), I didn't get my prescription refilled until the following Wednesday. 5 days late! Gah!
I know that sperm can live in the system for a few days. So I suppose my question is what's the likelihood I got pregnant if I had sex during my withdrawal bleeding/my HBC placebo week and he pulled out, but I didn't start my next pack on time?
Actually I guess the real questions are how long does sperm really live inside of a person? Does a person start ovulating as soon as they are finished their pack or does it vary from person to person? What's the likelihood of getting pregnant during withdrawal bleeding? And is there a Birth Control for Dummies-type site?!
I'm more curious than worried, I've been oddly fascinated by birth control recently! Thanks in advance. :)

Thus, the probability of pregnancy is very low if pre-ejaculate fluid enters the vagina."
Low does not equal zero. If you're that one woman in ten thousand facing an unwanted pregnancy b/c of awol sperm in Cowper's, the semantic difference between 'unlikely' and 'impossible' will be felt very keenly.
The bottom line is that even if most men's pre-ejaculate is clear of sperm most of the times they're engaged in coitus, there *are* times when it is present in it, and that is a fact that women and men should use in their decision making process regarding using withdrawal as a form of b.c. Even the page you cite to make your claim contradicts your stance: "the possibility remains that, in real life encounters, small amounts of sperm may be present in a male's pre-ejaculatory fluid."
All of this is not to nitpick, but to clarify what I felt could be a misleading and potentially dangerous statement.

Date: 2011-12-04 02:07 am (UTC)I appreciate your thoroughness and I'm glad you looked at the studies, but I would also remind you that every method of birth control has a failure rate. I never used the words impossible or zero. I think your initial comment was alarmist, especially presented as it was to a person using withdrawal as backup. You seem to indicate that even use as backup is unacceptable, suggesting that HBC with condoms will prevent another scare, but the significance of switching withdrawal for condoms as a backup to HBC is pretty small once you do the math.
Birth control pills do not prevent ovulation 100% of the time, but you did not see the need to remind the OP of that. I think it's important to be realistic about the failure rates of all methods--for withdrawal that's 27% with typical use and 4% with perfect use. For the pill it's 8% and 0.3%. For condoms it's 15% and 2%.
