Hoping to be pregnant in two weeks. period started august 2nd ended the following wensday. i guess i ovulated the 15th i had sex three days before?

See details: It is possible to get pregnant if you had sex 3 days prior to ovulation. The sperm can survive in the cervical mucus even up to 5 days.

Wait for menses!: If you are trying to time ovulation ,you need to know your average cycle lengthi.e.the 1st day of 1cycle to the 1 day of the next cycle.take 3months divide by 3toget average length.subtract 14 from that cycle length.This will give you an idea of when ovulation occurs
