Pregnant and need answers

[seek2understand]

On Sept 30th I had an ultrasound by my doctor and was told that I was 7weeks and some days right at 2months just about. This was a shock to me considering I wasnt excepting to be that far along. Im not sure if he told me the actual gestation age or the fetal age. Its important that I know because  I had intercourse with my steady boyfriend at the time the latter part of July then I moved out of town. I thought I had a menstrual cycle in august (around august 16th) but it was a little early and came and left before it was supposed to start for that month. A week later I (the last week of august) I had intercourse with someone else. I found out by home pregnancy test that I was pregnant Sept 22nd I assumed I was 4-5 weeks when I went to my first doctors visit. He gave me a due date of May 14th and when I asked when supposed conception was he said aug 20th which incorrect way to early for the latter guy and too late for the boyfriend. Who is most likely the father?

Ultrasounds can be off by up to a week and sometimes I little more then that. Unfortunately you'll just have to wait until the baby is born and get a paternity test.

I would say the steady boyfriend.  My LMP was August 16 and I'm 8w6d pregnant today.  On September 30 I was 6w3d pregnant.

It seems to me that it is most likely the steady boyfriends baby
