I had sex on March 17, 2010 and the condom broke. On March 18, 2010 I took the plan b pill. I dont remember when my period came down. I am estimating around the 22nd or 23rd of March, now it is May 5, 2010 and I just found out I am pregnant. My question is could it be from a recent occurrence or is it from March, the catch to this all is the guy I had sex with was not my husband and I am afraid, because me and my husband have been having sex alot since that time. Is it possible the baby is for the other guy? Please give me an answer.
