my last menstrual period was around august 26th 2009. i am currently 39 weeks pregnant...which is going by the ultrasounds. the first ultrasound i got i was about 6 or 7 weeks pregnant. they said my due date was june 7th. then the next one i got i was about 12-15 weeks not sure exactly but they said i was due june 2nd. i had sex with my ex in august and in september quite often. we had sex i believe on september 8th and 9th and 13th and 17th and 18th. but then i started seeing someone else and we had sex on the 26th of september. and the 5th of october. is the ultrasound accurate and if it is would i be pregnant by my ex or the guy i had sex with on september 26th? they said i was more then likely to have conceived on september 9th but is that accurate? and if i had sex on september 26th and it was his baby then how far would i be if it wasnt my ex's? i ddint get my period in september at all.

Based on a last menstrual period of 8/26/09, your due date is June 2.  If you are saying that they are coming up with the same due date based on your baby's measurements, then I would say it is your due date.  If those 2 match up, that is a pretty sure sign.  If you have a regular 28 day cycle, you would have conceived on or around September 8 or 9.  So, it seems unlikely that you got pregnant from your sexual encounter on Sept. 26 or Oct. 5.  Ultrasounds are pretty accurate.  They can be off a little bit, but to be off by over 2 weeks, especially early on, is pretty rare.

If you got pregnant from having sex on 9/26, you would be due around June 20.  If you have regular 28 day cycles, however, then on 9/26, your period was already late, which would again suggest that you were already pregnant.  

The only way to know for sure is to have a paternity test done.  Best of luck to you.
