Pregnancy Due Date Calculator: Estimating Conception Date

Question
im due april 18th when did i get pregnant?

Answer
Assuming you have a normal 28 day cycle, that you ovulated right on time, and that there were no circumstances or medications which delayed or triggered ovulation early or late, you most likely conceived between July 24th and July 26th.

Please let me know if I can help you further or with anything else.
