Bleeding after intercourse 37 weeks pregnant

I have a question for the community!
I am 37 weeks pregnant. My fiancé and I had intercourse today and right when we were finished we noticed a good amount of blood. Looked like the start of my cycle almost (so y’all can gage the amount I’m talking about). Almost 4 hours later and I’m still spotting but the amount of blood has decreased but still light spotting now. No real contractions. A couple Braxton Hicks I would say an hour or so after but nothing now. I feel baby kicking and all so no worries there. This is my second child. With my first I had a vaginal delivery but never experienced any bleeding prior to delivery. I don’t want to go to the hospital to be turned around. Anyone experienced anything like this?
