So, here is my question I had my period on june 3rd, I have one night stand with a friend (something I regret so much)in june 16,  then I had my regular period again on june 26th, I had sex with my bf on july 7-8th I found out I am pregnant on july 26th, I had my first u/s on august 27th baby measuring 9w4d (lmp 8w6d) And now in sept 17 I had my NT ultrasound baby measuring a week ahead (12w6d) but according to my lmp i was 11w6d. Can someone please help me! Im going crazy thinking who is the father of my baby.

Yes my periods are very close always between 23-26 days cycle never 28+
So the calculations above shows an ovulation date of july 4th... but I only had sex on the weekend of july 7-8th.

Are your periods usually this close together? If you had one on June 3, 2012
and another on June 26, 2012 (24 days apart)

You had your period after july 27th26th right? Cuz women can't have their periods if they are pregnant... I think toriiee is the best person who can help you out
