Okay , so I am having trouble with knowing who my unborn babys father is. And I talked to my Ob doctor and she did not help at all. My story ; Well me and my boyfriend broke up for 4 months , I had sex with my guy friend Sept. 10th 2010 ( he pulled out ). Then around Sept. 23rd I got my period , my periods are always irregular , but always 28 days of a cycle and there was blood . I'm hopeing it was't implantion bleeding. Me and my boyfriend got back together during my "period" and was having sex and he would ejculate inside me. ( sorry if too much info ). Then I missed my period in Oct. I went to the Doctors and they did an Ultrasound on Dec.11 2010 and they stated I was 12 weeks pregnant. My next appt. on Feb 4th 2011 I had an Ultrasound and they said I was 19 weeks pregnant ;[ Due June 29th ]. Please give me the most info you can , my Doctors are no help and I'm stressing .
