I've always been having sex but my cherry has already popped but this time we done it i bled a lot why is this but i never get my period?

A cherry "bomb": Your cherry (hymen) may have already "popped" like a firecracker of the same name, but without a period you may be exploding with a unwanted pregnancy. First obtain and use an pregnancy test, and if negative see a GYN MD to see if you have a vaginal laceration((bleeding cause) and acquire contraception so the rest of your life will not "explode" with undesired pregnancies.
