I Was 4 Wk 3 Day Pregnant. Acc To My

I was 4 wk 3 day pregnant. Acc to my Doc, it stopped growing and became flaccid, may be a part came out as a clot in bleeding. They could locate only 2mm inside. I took 3 misoprost vaginally yesterday afternoon and 2 today morning but I have very light bleeding like last day of periods, no clots and very mild cramps. Is it because pregnancy was very small or because it's not terminated. Should I wait for more time?
