BLEEDING DURING SEX!!!!!

So me and my bf had unprotected sex about 11 days ago, and we were having sex today and I started bleeding. I would’ve brushed it off as bleeding from sex, but I felt cramps similar to light period cramps for the past 2-3 days. My bf said he doesn’t think I’m preggo and neither does his mom, but I’m kind of nervous. I was planning on taking a pregnancy test after two more days. Any advice or ideas of what’s happening? 😩🤦🏾‍♀️
