Should I be concerned?

This may be TMI but, everytime after husband and I have intercourse it seems that most all of the ejaculate leaks back out. We've been TTC for 6 months now and I'm starting to wonder whether I should be concerned about this. I've tried to lay still for 15-30 minutes but it doesn't seem to help. Should I be seeing my doctor for something like this? Thanks for the advice! Really looking forward to being a mom!
