Who’s the father?

Patient: Could my ex be the father of my baby if we last had sex 6 months before my actual date of conception? I’m due July 23, 2011. Doctor told me I conceived October 16, 2010 and last sex with ex was April 2010. I’m stressing about this, please help! Thank you!

Doctor: It is not possible that your ex is the father of your child as your date of conception is way after you last had sexual intercourse with your ex. I hope this helps.
