Pamic and TMI

I am 9 weeks. My husband and I had sex last night. It wasnt exactly slow and tender but it wasnt rough by any means. It definitely wasnt any different than usual for us.

Anyway we got done got up to clean up and i had a huge spot of blood where I was. It/we looked like a scene pinned for murder... I dont hurt... other than feeling like I pulled a muscle. This was 2AM. I decided to go to the ER. Spent 5 hours a pelvic exam blood test and an unltrasound later they say baby is fine didnt find anything concerning and i could go home. At that point the bleeding had dialed down. Well here it is 1pm and the blood is picking up. I am panicking... Again I am not cramping... Has anyone experienced this and it turn out okay??
