A member asked:

Due date 12/22/13 when was this baby made? conception? ovulation? don't have regular periods. lmp 1/20/13-2/15/13. how long does sperm live (max)?

A doctor has provided 1 answer

3/31: You are quite a way off.... If your due date is 12/22, then your 'average' date of conception is 3/31. Lmp would have been around 3/17. It's possible your due date was off.... But that's only if you had a 2nd or 3rd trimester ultrasound that gave you your dates. If you had a 1st trimester us then due date is good. Sperm lives for about 72 hours.
