is this a miscarriage?

So i got my period two days early last wednesday, it was bad. I've been clotting, fainting, crying from the pain and bleeding through super tampons and ultra pads in two hours. The bleeding is only really light now but my stomach is still so sore and i have pain in my left side on and off. I went to the doctor today and he told me there was a chance i could have been pregnant, but very unlikely i am now, however he told me i should wait at least a week to test just to be absolutely sure. does this sound like a miscarriage or just a really bad period? Also if i was, is there still a chance i could still be pregnant?? 😢
