We had intercourse for the first time and it was unprotected and she had her period after that time. Then, foolishly, we had unprotected sex again and took Plan B that time as we were both very worried about pregancy. We weren't aware that if you have intercourse after taking this it decreases it's effectiveness tremdously( or so says the planned parenthood personel). I would imagine that if the pill is the larger dose of the normal birth control pill it would shed the lining and move that egg down. So, i am confused on two things...how is it that it is rendered ineffective after taking it and then having intercourse again... and how effective do you think it is if we have never even gotten close to ejaculation. Obvioiusly there was minimal pre-cum and there is no garuntee on the sperm contained in the lubrication state of precum anyways. I know there is no "for sure" answers for these questions and I, as most everyone else on here, am just looking for some reassurance from some at least somewhat closely related expereinces. So, anything will help. Thanks-
here is a timeline of the events to give you an idea.

period-12th
intercourse-18th
19th
20th
Plan b taken- 20th
intercourse - 29th
30th
31st
plan b taken- 31st

*Keep in mind it never even reached a "pull out" state. I never even felt clost to coming while doing this. we averaged an intercourse time of 10-12 min each times and sometimes less. Oh and everytime after she cleaned her self out and washed with warm water. we made sure to do that everytime. cleaning almost all liquid substances out. Drying it all up bascially.
