Rachel copulated with Micheal and didn't get pregnant on ovulation.Explain why with plenty reasons
Predicting or tracking Ovulation is not always accurate, so there is good chance if you wait to O day to engage in sex it may be to late to fertilize the egg.
Also it worth noting that O day is not the highest change of pregnancy.
If you really want to have a baby you need to be having regular sex from the week after she finishes her period up until the week before her next period. In the middle of the cycle ( say days 10 to 18 on a 28 - 30 day cycle), it is best to have sex everyday or at least every second day. Be sure that he drives himself deep inside her when he cums (this way the semen lands near the cervix) and hold it in there for a few minutes to allow all his sperm to run into her.
She should then lay on her back with her hips elevated for a few minutes so the sperm run down into the cervix.
