My bleeding with my ectopic was pink and red with no or very little clots (my normal period is very clotty) it also had alot of mucous with it. It also wasn't painful like even my normal period was let alone a m/c. After this happened to me I learnt its quiet typical to have bleeding like this around the time your period would be due or at the 5week mark or else a prune juice kind of discharge. This leads alot of women to not even know they are pregnant as they mistake it for a funny period.

An ultrasound with a BHCG under 1000-1500 which most likely show nothing. Maybe worth having but I would be surprised if it would show anything at all. Where I work in another week or two if your levels are slowly rising and not going down they would usually treat it with methotrexate if the ultrasound showed an empty uterus.
