Hi!
The bleeding is probably due to your menstrual period. It would be unusual for bleeding from the hymen to persist so long. Whenever there is intercourse, there is a chance of pregnancy, and I ALWAYS recommend doing a test. I also recommend taking precautions against unplanned pregnancy and sexually transmitted infection. Condoms are a good choice!
Good luck!
