Do I need to get this checked out?

Okay, so while my SO and I were enjoying some very intimate time and we had just finished having sex, we noticed that I had started bleeding. I am not due to start my period for another 9 days. Also, I am on the birth control pill Reclipsen and have been on it before and never had an issue with it, but I read on the label that one of the side effects may be bleeding. Do I need to get this checked out?
