Conception date??

I hade sex with my husband alot in October and I did a huge mistake and had sex with a guy one time on October 28th and he pulled out. I'm currently 9 weeks 5 days pregnant. My due date according to my first ultra sound is July 29th. I had my second ultrasound and they changed it to July 23rd now they are going back to the 29th. I'm just trying to decide when I conceived???!!!!

I would think your ultrasound should be fairly accurate, at least within the week, given how early they were done. But you can ask your OB to be sure.

They did an ultrasound on november 21st and said I was 4 weeks. I did another ultrasound 2 weeks later and said I was 7 weeks. I went back again last Wednesday the 28th and they didn't do an ultrasound but they said they were going with the first ultrasound. So today starts my 10 weeks. So could that be the "week off"?

Also, it's difficult to say when exactly you ovulated. I apparently ovulated about a week later than your average woman, but my cycles range anywhere between 30-40 days. But when they initially dated me based on my LMP, it gave me an inaccurate conception date because the assumption was I had an average cycle. I had an ultrasound at 5 weeks and then again at 6 weeks that gave me a more accurate due date.

It depends on how early the ultrasound was done. At the very early stages of pregnancy, they're pretty accurate because in the earliest stages the baby follows a very specific development patter. But the further along you get the more inaccurate they are in their estimate. If your ultrasound was done at 6 weeks, it's probably very accurate, at 12 weeks though it could be a little off. I think they say they can be off as much as a week or so. In the second or third trimester though, it could be off more, as babies grow at different rates after the first trimester and ultrasounds date based on what the average baby development is at that particular date in the pregnancy.

My cycles are usually 30-35 days. So when they tell you how far along you are in an ultrasound then that's basically when you conceived give or take a few days? I took a test the week of oct 26th then another one on nov 4th. Both negative. On November 7th I started getting symptoms, sore breats and fatigue. I took a test nov 14th and positive.

Based on your LMP you should be due a lot earlier than what you are. Like in the first week of July not the last. Unless you have long cycles or ovulate later on.
The earliest ultrasound is usually the one that is most accurate for dating purposes but you are going on a close call here.
Chances are that if you had sex with DH a lot and the other guy pulled out, it is more than likely your husbands but never say never. The only true way you would know is a DNA test.

Your conception date would be at the start of november but your safe bet would be to do a dna test if your not sure good luck
