My last period was May 26th 2008. i was in a serious relationship but we broke up on june 1st. I ended up having sex with an old friend the 7th and 10th of june ( the 10th we used protection ). and then got back with my ex on the 13th. i know its really confusing but now im pregnant and im not really sure what to do. All of the ovulation calculators say i was ovulating on the 12th. Ill be 10 weeks pregnant monday. and My cycle is 31 days long not the usual 28. can someone please help me.
