MTX for ectopic and vaginal bleeding

Ch

I was diagnosed with an ectopic pregnancy on 11/18 had methrotrexate on 11/18 and 11/25. I’m still having vaginal bleeding. Anyone that has had this shot before, how long did you bleed for? My hcg levels were at 47 on 12/16 so I know it’s not my period. I go again for hcg check on 12/23
