Bleeding after sex 36 weeks

Lauren

I’m 36 weeks pregnant and bled a lot right after sex. It was dark/ bright red and falling into the toilet, not just when I wiped. L&D told me to go ahead and go in but they say that every time I call. I called a different hospital and they said as long as it’s not active and I’m not filling a pad that everything should be okay. Has anyone ever had this happen?
