Bleeding after intimacy

Alisha

So last night my guy and I were going at it, it’s been a couple weeks due to blocking children lol but when all was done I was cramping pretty good and there was a good amount of blood. However, I know the blood could have looked like more due to the cum. I rinsed off and laid down. The cramping subsided and the bleeding was gone by morning. I am practically 32 weeks pregnant. Thoughts? I do plan on asking my dr at our next appt.
