Stressed.

[confused23988]

So I am confused about who could be the father of my baby.  I am not 7 months pregnant. My first day of my last mensutral cycle was Sept 23 2012.

I had sex with GUY A Sept 21st and got my regular normal period sept 23rd. It was not light or short. It was heavy and normal just like always.

Then after my period I had sex with Guy B many times up until I found out I was pregnant.

Now I've had two dating scans.

On Nov 7th the told me I was roughly 6weeks and a couple days. Then on Nov 29th they said I was 9 weeks and a couple days.  I believe at my 12 week ultrasound my baby was mesuring correctly too.

Up until now they never changed my due date but now they are saying that my baby is mesuring with a due date of June 21st but they will keep my June 30th  due date.  
I caculated that if my due date is June 21st that means I concieved around Sept 28th.

Who is the father?

GUY B.

Guy B.

1.  You had a normal period after sleeping with guy A.
2.  You had an early ultrasound that said you conceived in early October, probably sometime around the 8th.  That ties back to your period beginning September 23, as it did.
3.  Due dates are not reliable if the baby is measured later in pregnancy because babies grow at different rates.
4.  Even if you did conceive around September 28, (which you didn't by your first two or three ultrasounds and those are the only ones reliable for dating), it was after the period you had after sleeping with guy A.
