Hi, I have the same situation but my baby already born and he has no resemblance to both of us. And now im figuring who the father might be. I had my period last oct. 5-8, 2015 and had sex with ex on oct. 15 and with my current bf on oct. 17, 18, 20, 21, 22 and the rest of oct. and nov., im expecting to have my period on the first week of nov or second but i missed it so i took pregnancy test on the 4th of nov and turns out negative. I took pregnancy test again on nov. 19th and it turns out positive. When i had my first ultrasound on dec. 11, i am already 7 weeks pregnant and my due is on July 25th but i successfully delivered on July 13th like 38wks and 2days or 39wks. Could there still be someone trace who the father might it be?
