So my hubby had a vasectomy just over 4 weeks ago. Due to lack of effective communication between the 2 of us we now both regret it massively. We were told when he had it done that we were to use another form of birth control for 3 months as it takes this long for existing sperm to leave. Now my question is we are thinking of trying our hardest to conceive has anyone gotten pregnant after a vasectomy within this window or are we really clutching at straws?
