Hcg levels and no period

Chelsey
If my HCG levels was only a 2 last Wednesday and I've only spotted on and off a few times does it mean it's done or do I need to go back to the Dr? My levels only went up to 11 in 5 wks but were down to 2 last week but I'm still not bleeding or cramping so idk what's goin on. Anyone else dealt with this
