5 weeks brown spotting? Help

JC

I’m 5w2d and started spotting this on Friday night. Off and on. Went to ER and they don’t know if it’s a miscarriage or not. The ultrasound showed a gestational sac. No blood so they don’t know where it’s coming from. Had an ectopic last year and a miscarriage on New Years.

Anybody else have this?
