I'd go with the notion that it was the person you had sex with on the 20th. Ten days before is just a few days too far beforehand, for it to be that other person. For the sake of your child, you need a DNA test once the baby is born, to be sure.
Have you had or will you have an ultrasound soon? If so that would really help you narrow it down, early ultrasounds are pretty accurate, a lot more accurate than just estimating from your last period. Not every woman ovulates at the same time, and they assume you do when they give you that initial date.
I would guess the 2nd guy, I am 1 month behind you, my dates are due sept 13 and conceived December 24, but they are jus guesses
It just occurred to me with an August due date you're pretty far along. When was your first ultrasound, and what was the due date they gave you from it?
I know u tried the Google calendar but heck out the My Days app. It is very thorough. Also, I would guess the 2nd guy on the 20th. It can tell u if u were even fertile or ovulating 10 days beforehand. I am due Sept 12 and know for a fact I conceived dec 25.
Thank you guys for your answers an yess ive only had one ultrasound an from that i am 26 weeks i will be 27 next week so i did count back from that an it came out to be the first guy i had sex with im soo confused i think im more confused on if i should count 40 weeks or 38? I will get a DNA test but not right away for im scared to even know muself but thanx ill also try that app you have mentioned.
You count back 38, the first two weeks of pregnancy is before conception...just remember that sperm can live inside us 5-7 days so whatever date you figure out, it's still better if you get that DNA test because you could still be wrong. Hope this website helps a little...I love it, just replace my due date with yours:
