Period almost due, Precum? Plan B. Pregnant?

So here is the story, me and my boyfriend started to have unprotected sex even though we both knew it was a very bad idea. I had a bad feeling so I suggested we stop, and while I told him this we had paused... but then he started to contract. He imidiatly pulled out. We don't know if he precumed or what happened. Also, I was suposed to start my period that day, but my period is rarely on track anways... so my question is, if he did happen to precum, would I get pregnant if i was about to start my period anyways? My boyfriend said it wouldn't matter since I am releasing eggs anyways, but boys always think they are right. Now we've been in a similar situation, and we turned to the pill 'Plan B'. It says to take up to 72 hours of unprotected sex, well it's 72 hours right now but i can't buy the pill till tomorrow, so my next question is will it still be affective? We are both worried sick. Please, we need your help.




Also... do you have any idea why my periods aren't on time? I do the whole count 28 days thing but it's never on time. Is that because of stress?















OH MY LORD. I STARTED. I'M SOOO HAPPY
but please reply still... I'm still interested and I'm sure others are too
