Who's the father?

When did I get pregnant? I had sex July 6th. We broke up about a week later. I had a regular period in august. I started having sex with a new guy middle of august. Missed my period September. Tested in September and was pregnant. Ultrasound confirm due date June 6th.

Or, it would not have been caused by the pregnancy with the due date of June 6, that is.  (I just noticed that you haven't put years on this.)  Are you pregnant now or are you trying to figure out the paternity from an earlier pregnancy?  If you're pregnant now and due in a couple of days, it's easy to rule out the July guy because you would have to be 11 months pregnant if the sex you're worried about is July 6 and today is June 4.

Thank you. I had my baby 5 weeks early. I had him may 5th 2016. He was a premie.

If an 8th-week ultrasound said your due date was June 6, it would indicate you conceived in mid September, not earlier.  The missed period earlier in September would not have been caused by the pregnancy you have now.

I was 8 weeks along at my first ultrasound.

Do you mean you are due in three days?

Was your period that you missed in September expected rather late in the month?  Because the conception calculator I use says you would have conceived at the middle of September if your due date is June 6.  How early or late in the pregnancy was the ultrasound that gave you the estimated due date?

My missed period would have been on September 4th. But i had a period in august after i had sex with the first guy.  They didnt see me until I was 8 weeks along.

At what point in the pregnancy did the ultrasound happen that gave you the due date?
