I'm in a real dilemma here. My due date is March. 14th, 2012...my last period was June. 7th, 2011 and my cycle is on average about 34 days. I had sex with this guy that I slept with only once with no protection, but, he pulled out on June. 24th and I slept with my ex boyfriend who I've been sleeping with for almost 2 years with no protection ever at the time on June. 25th and he ejaculated inside of me. I'm not sure who the father could be, any way I can find out. I'm really hoping that this baby belongs to my ex boyfriend. According to my due date I'm 17 weeks, 5 days...haven't gone for my ultrasound yet tho. Help
