I am currently 17 weeks pregnant, & unsure of who exactly the father is. My due date is 4-22-13, and I have had two ultra sounds. The first ultrasound said i was 13 weeks and 4 days according to my doctor. The second says 17 weeks now. Me and my ex fiance broke up around july 4th, and i met a man earlier that year who had always liked me and i decided to date him after the breakup. Me and my current boyfriend (not the fiance), had sex without a condom july 15th-19th, but he pulled out each time. Then on july 24th would have been me and my ex fiances 5 year anniversary so while drinking away some of my bad feelings he calls me and i make the mistake of sleeping with him. On august 17th I find out im pregnant. Now heres some background on me and my ex fiances sex life: We have been trying to have a baby for two years, and i have never gotten pregnant, not once. I always thought it was me, (But its obviously not) but is there a chance that now we had sex the 24th the same way we always have that I am pregnant with his baby? July 15th-19th or July 24th? this is a hard thing for me to solve. I dont know who the father is and i would like opinions that aren't to harsh. Seventeen weeks ago was july 19th, when i had my first ultrasound 13 weeks and 4 days was july 15th, but everytime i googled what could be my possible date of conception it says i wasnt ovulating until july 22nd-26th. Can somebody help me? keep in mind that my ex and i tried for two years. Thanks, -Jen
