i am going thru the same thing. the first day of my last menstrueal period was august 12th-17th or 18th. I had unprotected sex with a guy on the 22nd he did not come in me. we stopped and i gave him oral then he cummed on himself. i had sex with my boyfriend on august 23rd and august 26th. on my period/ovulation app it says i started becoming fertile from august 22nd-27th. i didnt see my period in september so i went to the emergency room and they said i was 5wks 2days. making my conception date august 26th the same day i had sex with my boyfriend, i feel like its my boyfriend since conception is the exact day we had sex plus i have been tracking my period for a few months now and i knew i would be fertile that day and my boyfriend and i planned to haves sex that day. i feel like the other guy is not the father, but i know precum could have been present, plus my boyfriend and i have been trying for a year and a half now. a year and a half ago i had a 3yr implanon removed so we could try. this would be my boyfriends first child we are both 30yrs old. in the past he said when he was younger his brother had kicked him in the balls and the doctor told his mom he was sterile when he was round 5yrs old. but in the last 5-7 years before me he has gotten two other girls pregnant. one was a miscarriage and one was a still born, but both times he was either incarcerated or not living in the state and they could be possibly lying. from the dates does anyone think that he could be father? i know god can work in mysterious ways i aslo only have one ovary so i know it takes me a little longer to concieve. im just hoping it is my boyfriend we have been trying and now im 7months pregnant. i couldnt abort the child beacuse we did have sex on the exact day of conception. and i made a promise to god that i would not abort this child because of previous abortions. and also prayed months before this if god got us pregnant i would keep it. so what do you guys think, my boyfriend or one night stand?
