miscarry

went to kkh 24hr o&g clinic bc i had bad cramps and jelly blood. I alr knew I had a missed miscarriage at week 6, I was expecting the bleeding to come any time. after the doctor check and all confirm my body is trying to expel the baby out.. now 4hrs ltr, in bleeding suoer heavy changed (2 pad within 30mins), having extremely painful cramps kind of feels like contractions. not sure if i went back kkh what help would they be since I wanted to let it pass naturally. not sure what to do as well. I keep staining my undies as the blood is too much.. and it rly sucks bc the "contractions" is feel like taunting me i lost my baby
