Understanding Conception, Birth Control & Unexpected Pregnancy

Question
I had sex with another man on October 17th.,2008 we used protection and then although it didn't break, just to be extra safe I had b-plan pill 6 hours later. I had my period around 23 or 24. The had mostly unprotected sex with my bf all november. Had pregnancy test at home around 12th-negative and then 19th in the clinic(urine test) - negative. On 13th of December found out they us scan 7 weeks pregnant, which basically dated back to my period. Due date was august 2nd, I delivered on the 10th. What are the chances that the baby is not my boyfriends? Even after having all the protection!? I know it sounds really crazy but I'm going nuts thinking it might not be his baby!  Thanks!

Answer
Megan,


It's your boyfriend's baby.  Period.  You had a period after you had intercourse with the first man, which should tell you right there it's not his baby.

So, the chances are virtually 0% that it's not your boyfriend's baby.




Best,
