Miscarriage pill…heavy bleeding 😓

ab

I was 7w when baby stopped growing and it was classified as incomplete miscarriage since I has no bleeding so I was prescribed misoprostol…I passed the fetus 4 hours after taking the 4 tablets and am having heavy bleeding and big blood clots ever since I even went to the hospital since I was soaking up maternity diapers in less than an hour…they said the bleeding is excessive but still considered normal since all my bloodwork came back normal and I did pass fetus and majority of the miscarriage…my question is do I take 2 tablets every 8 hours like prescription says? Or can I let the natural process take place? I’m kind of scared of more excessive bleeding but don’t know if I should listen to the directions…😓😢
