Sperm leakage ? Help!!!!

Has anyone experience sperm leakage and still gotten pregnant?! After hubby and I bd I laid there for awhile. But when I got up to use the bathroom. Sperm came out and a lot of it. I think I flushed an opportunity down the toilet. Maybe I should of had my legs up and waited for a while. Why is it leaking out of me is something wrong with my vagee?
