bleeding and cramping at 6wks

Carly
So I'm only 6wks preg. Blood test on the 18th positive. 21st had some bleeding and cramping. And still some bleeding today. This would line up to when my period would be if I didn't have a positive test. So I'm assuming it's a miscarriage but would have thought there would be more bleeding. Prob can't get in to see my doc for a week. So that will be some nice thinking what's going on for a week. Or should I go to the ER? Then I guess I would know. Anyone else have that scenario?
