When i get a positive opk result in the morn, should we make love immediately or is it ok to wait 12 hrs before we see each other again that nite?

How to get pregnant: If you ovulate and there is no sperm inside of you there will be no pregnancy. I am not sure why you are using a test that is flawed for this important experience. But, here are the more simple rules. Figure out the day in your cycle (sully day 13) that you ovulate. The count back five days. Those five days are when sperm will cause pregnancy. Sperm left on the day of ovulation or after may not.
