I had a period from May 3 - May 6. I had sex with guy A on May 16. I then had another period from May 27 - May 30. I had sex with guy B all of May and June. Guy B and I don't use the pull out method at alll.. Guy A said he never came in me. I think Guy B is the father but I can't help it I'm worried. I am currently 24 weeks pregnant and I'm due on March 3, 2014. So far my due date is matching up with my last period..

It would make sense for your due date to match since your doctor will be basing your due date partially on when your last period was. If you had a period after Guy A, then its Highly unlikely Guy A is the father. So unlikely that I wouldn't even bother testing.
