Spotting for two days

Not sure if I should be worried or not. The blood is reddish brown and is much lighter today than yesterday. No cramps. I only see the blood when I wipe. I had an orgasm yesterday (no sex though) and noticed the bleeding start shortly after that.

My doctor’s office is closed over the weekend so my only option is to go to the ER. Should I go??

Just want piece of mind to know if my baby is okay or if I could be miscarrying.

I’m 9 weeks pregnant.
