Miscarriage remaining blood clots seen inside.

Hi po , i went through miscarriage last Saturday and it was really painful. Marami po lumabas na tissue sa'kin. They instructed me to go through TVS ultrasound. And yung result po is "Complete Miscarriage" but meron po konti daw na blood clots inside sa womb ko. Sabi po ng nag tvs sa'kin d na daw po kailangan mag pa raspa since ganon nalang po natira. But right now, im having painful cramps in my cervix area . Pero walang lumalabas ano po kaya dapat gawin? Any advice po ?
