bleeding stopped

i was taking the pills to start if miscariage bc my body didnt do it a d there was no heartbeat and measured small. I took all 6 doses i was supposed to and only was bleeding a little bit not much to even fill 2 pads in the last day a d a half. Im not sure why the bleeding stopped? really wanting this to happen natrually or with tge pills so i dont have to go through the surgery but not sure why the pills arnt working.. i have no clots or anything like that just a light amount of period like blood.

Iv been laying down pretty much the whole time only got up to go to the bathroom, my husband thinks bc im not moving around enough maybe stopping me from bleeding like i should? the pills have made ne so nausous its all i could do though, im not suppose to take anymore doses.. just want ways to help the blood flow start
