Who could be the father? HELP!!!

I made a stupid mistake and cheated on my longtime boyfriend. This was the very first and last time. I had unprotected sex with a friend August 22. My period is pretty regular so it came on September 3. It wasn't spotting. It was a heavy flow as usual & lasted about 6-7 days. On October 28 I went to the doctor where I got an ultrasound and found out I was 7 weeks 6 days pregnant. When I count back to that day it's the exact day I started my period. The conception date was from the week of September 13-21. I was with my boyfriend that entire week. Seeing as first trimester ultrasounds are pretty accurate does this mean my boyfriend is the father? Also has anyone tried the cvs process for a prenatal dna test?

If the ultrasound at 9w3d is for sure what gave you your due date, they will have measured the embryo and used the size of the embryo and its developmental markers as a basis for their computations.  This is more accurate (if they did use the ultrasound information) than any kind of forward count from a last period using a calendar.  From the due date you have been given, you can count back 266 days to get to the estimated conception date.  (Or use an online conception calculator.)  In the ninth week, there is a small possible margin for error when using an ultrasound to try to determine when conception was, but it is not as big as 11 days.  It's more like 2 or 3 days, possibly 4 at most.  This makes it seem pretty clear that the baby is not from the sex on the 13th.  Talk to your doctor about this and he or she should be able to confirm that ultrasound information was what was used to determine your due date.

And it was at that appointment, at 9 weeks 3 days, that they gave you the due date?  If so, it sounds like March 13 was about 11 days too early to produce the pregnancy.

I think March 13 would be too early to produce a baby if you are 20 weeks pregnant now.  Do you have an estimated due date?  If so, how did you get it, was it from an ultrasound?  If so, how many weeks pregnant were you when you had the ultrasound?

If the baby is measuring 7 weeks you should be fine. The technology these days are so spot on and acurate. Id say its your boyfriend. Good luck and congrats

But the ultrasound said she got pregnant AFTER her period. So your boyfriend is the father.

Very hard to say with my first pregnancy I didn't know until I was 3 months because I had periods for the first 2 months so you should talk to your significant other and get a DNA test

First off to all the people who said it's the boyfriend because you had a period after you mistake, don't listen to them....
Although I have never and will never cheat on my husband when we were trying for our first (that finally happened after 6 months) I didn't know I was pregnant until a few weeks ago.
I was already 2 and a half months pregnant when I found out. I had 2!!!!!! Periods. My first was regular but my second was only 3 days.
8 went to the hospital for asthma and they tested me and it came out I was pregnant so yes I am sure I'm pregnant I've seen my little one on many ultrasounds.
My doctor said it is! Possible to have periods while pregnant especially in the first few months.

Second! Do a DNA test..... it saves YOU and the REAL father some troubles.
Cause what if your boyfriend isn't the dad and raises that child? It's not fair to either.

Also does your boyfriend know you cheated? That's something that should be discussed if not already.

Your boyfriend is the father for sure. You wouldn't have had your period after August 22 if the other guy was the father

Doesn't like you have anything to worry about. Pregnancy weeks are worked out from the first day our your last lmp, which you've confirmed, so ovulation days were with your boyfriend.
