[girlygirlxoxo]

Hi everyone, im 26 weeks pregnant tomorrow.. and i have a little problem well me and my boyfriend broke up for a few months back in july/august. i was with a guy on august 10th, we were drinking we didnt have sex but he tried to push it in for about 5 seconds, i was really dry(sorry TMI) so we stopped, he was no where near ejaculation. then on the 15th of august me and my boyfriend got back together and we were having sex every night from then on with him ejaculating in me.. i took a pregnancy test on september 7th and it said positive.. i had an ultrasound the 17th putting me at 5 weeks. EDD:may 20th. i had another one at 8 weeks, but i was measuring 9 weeks EDD:may 13th.. also one at 12 weeks that was a day behind my 9 week ultrasound. all of these ultrasounds put my conception around 18,19,20,21,22. so i was pretty comftorable ruling out my boyfriend as the father. but then on my 20 week ultrasound i was measuring 6 days ahead EDD: may 7 putting conception august 14th.. but the problem wit hthat is i wasnt w my boyfriend until august 15th..so what do you think!?i would appreciate some help.. who do you think is the father

unless she is like me and ovulated early i had my last period on 30th of july was my 1st day i was preggy on the 8th of august so best way is dna

Hey hun, May 7th is my due date too!! And They say I conceived around the 9th through the 15th. so if we have any where near the same length of a cycle than that would be right for you too.  I have abut a 28 or 29  day cycle, my cycles would very.  it could also go past the 15th.  and considering he didn't ejaculate at all and it was that dry, I highly doubt there was any pre *** either.  Especially if it was only a few seconds, my bet is that its your boyfriends... I really think there's about a 98% that its your boyfriends, considering the information you gave me.

DNA

Then most likely it's your boyfriend's baby but I'd still do a DNA test to know for sure.

they actually only gave me one due date and it was may 13th .. he told me it was accurate to within a few days. the first ultrasound i got was at a clinic. even tho it was measuring bigger at 20 weeks thy kept my due date the same. but i dont know my ovulaation date i didnt have a period for 2 months prior

It all depends on when you ovulated.  I am due May 8 and I received a positive OPK on August 17, so I ovulated some time between August 17-19, at the latest.  If your cycle was anything like mine, then it would definitely be your boyfriend's baby.  Since your due date has changed so often, I would think that they're basing your EDD on your baby's growth and not your last menstrual period.  My EDD is based on my LMP and also matches my baby's growth.  So since things are kind of uncertain and the dates are so close between your boyfriend and the other guy, I would say the best way to find out is to wait until the baby is born and have a DNA test done on the other guy and/or your boyfriend.  Depending on the result of either guy, you'll know who the father of your baby is.
