My ex-girlfriend got her period on Jan 11th 2010, we had sex on Jan 13th. We had sex again on Jan 22nd. The Doc said that we conceive twins and the due date was on Oct 20th 2010. She lost one fetus in the first trimester. we just had an ultra sound today (April 30th 2010) and the doctor said by the measurements of the baby the new due date is Nov 12th 2010. come to find out that she had sex with a guy that she started dating after in the being of Feb. She has not had a period since Jan who is more likly to be the father? and if i am the father why is there so much difference between the estimated due dates??
Oct2oth, It is likely that the due date will change when going from a dual pregnancy to a single pregnancy. The story does however sound a bit confusing and it is not possible to exclude you from being the father.
