Pregnancy Conception Date: Calculating Due Date & Conception Timeline

Question
if i am 25 weeks as of March 25th when did i get pregnant my last period was in Sept and i do believe it was coming on in October because i was having cramps but i had sex before when did i conceive

Answer
Dear Crystal,

If ultrasound has confirmed your dating and you were at 25 weeks on March 25, 2010, that would give you a due date of 7/8/10. However, it also estimates an approximate LMP of 10/1/09 and an estimated conception date of 10/15/09.

I hope that this has helped you and answered your question. I wish you well.
