I wanted to ask a question, sorry if it sounds a bit gross! After hubby and I have BD'd, the sperm usually comes out again later in the day. I was worried that if I'm exercising and it comes out sooner, it won't have had the chance to swim to the right place. I know that some sperms get there in just a few minutes but others take 12 hours, so assume I've given them enough of a chance (!) but wondered if anyone else encountered this? I asked the doctor but he just laughed and said it doesn't hinder your chances. However I've found that ladies on this forum seem to have more accurate information about fertility than some of the specialists I've seen!
