What’s happening???!

So my boyfriend and I been together for almost 5 years. On the 30th of July we have unprotected sex. After he finished he told me that blood was coming out. I figured maybe he went too deep & cleaned myself off. Later that day I began to get cramps nothing major but they were definitely noticeable. Awhile later I went to the bathroom to pee and when I wiped there was blood but there wasn’t any in my underwear. This continued to happen the 31st of July as well as the 1st of August. Now I just have dull cramps here and there and I’m not sure what’s happening. I cAlled my doctor but my appointment isn’t until the 16th 🤦🏽‍♀️ any clues what’s going on ? Has anyone experienced this ?
