Pregnancy Timeline: Estimating Conception Date at 32 Weeks

Question
ok i am 32 weeks instead of 33 weeks , i am due april 15 and my
lmp was i think july 15. can you help me now with determining
about when i had sex to get preg.
thank you

Answer
If your last period started on July 15, you probably ovualted on July 28. You could have conceived if you had unprotected sex on July 27,28,29, or 30. You are due on on April 22 and should now be 31 weeks 2 days (from the first day of your last period).  If your doctors told you  that you are due on April 15, then your last period must have started on July 8 and you could have conceived if you had sex on July 20,21',22, or 23. If so, you would now be 32 weeks 2 days pregnant.
