I am trying to figure out which time I got pregnant. I had sex June 4 then again on June 24 I am now pregnant about 8 weeks according to what a due date calculator is saying. My first day of my last period was June 9 so what intercourse caused this pregnancy? Please assist

If you had your last period after you had sex on the 4th then it can't have been the 4th providing it was a real and normal period. You usually ovulate and are fertile between 14 and 21 days after the first day of your period so the 24th would make the most sense. Please remember that I am not a doctor though. I am guessing here, but do these two dates refer to two different partners by any chance?

As Mrs_C said, if your period started on the 9th, and you're considered 8 weeks pregnant, it would most likely have been the sex from the 24th. Have you had an ultrasound yet? That will give you a bit better idea.

The 8 weeks is counting from your last period and most women will not actually be pregnant in the first week or two. This is considered the gestational age. After an ultrasound they may adjust the weeks a little and get closer to what the fertilizational age might be.
