5 weeks today and bled during intercourse at 4+4

Kristina • Mama to 2 boys & 3 step kids
I've had a miscarriage before. About a year and a half ago. It went from light bleeding, to cramps, to a heavy flow and then passed clots. It was obvious it was happening. 
At 4+6, my SO and I were having intercourse. Kind of rough as that's our usual. It was at night so the bedroom was dark. When we were done and went to turn on the lights and clean up, we noticed blood on the bed and sheets. Maybe the amount of a medium period. I think it got messy because our hands were everywhere spreading it. When I went to the bathroom to clean up, it was gone within a few wipes and nothing returned the next morning, or even at all. I've heard that bleeding during intercourse is normal because the cervix is sensitive with blood vessels but I wanted some advice from those who have experience miscarriages. I called my doctors on call yesterday and was told that it's normal as long as the bleeding stops but I'm still searching for that piece of mind. No cramping either. At least none worse that when I found out I was pregnant. Please offer some advice. I hope I'm not miscarrying again.
