Bleeding?

Isabella
So on Monday I had sex for the first time. Today is Friday. We had trouble getting his dick in but we finally did, with some pain. Afterwards there was a lot of bleeding. The full on bleeding stopped on Wednesday. But since then I've had weird brown goop coming out. I don't know if it's blood, discharge, or a mixture of both. Was it normal to bleed that much? Any ideas on what this goop is? Could it be because he came inside me? If you have any ideas please let me know!!!
