Don't Know who the father is?

[19Shelly88]

Can someone please help me. My LMP started on the 03/06/2010 and finished on the 07/06/2010, and my cycles last for 30 days each time. However with saying this I slept with a fella on the 11/06/2010 to the 13/06/2010 and I got with my partner on the 18/06/10. All the computer tests have told me I'm due on the 12/03/11 but with saying this I have had an ultrasound and they believe I'm due on the 10/03/11 but due to the length of the baby the EDD is the 04/03/11. I don't believe I could have been ovulating that early on when I slept with the other bloke. Please don't judge me, my doctor told me I could never fall pregnant and now I'm in this situation.

With regular 30 day cycles and a LMP of 03/06/10, you probably ovulated 18/06/10 and your due date would be 10/03/11.  Generally, sperm can live for up to five days or so inside you and your egg would have the ability to be fertilized for a period of about twenty-four hours.  If you ovulated 18/06/10, that means that the egg could have been fertilized by sperm deposited into you anytime between 13/06/10 and 19/06/10 give or take a day.  Since you were with one guy on the 13th and another on the 18th, this egg could have been fertilized by the sperm of either of them.  Because of this, the only way you could know for sure who the father is would be to have a DNA test done.

I agree with the above poster, there's no way to tell the dates are too close. Sperm can survive for up to 5-7 days inside you, so there really is no way of knowing. You will need a DNA test to know who fathered your baby.

The only way you'll know for sure is to get a DNA test when the baby is born.
