Misscarriage 😔

Went to ER Monday night with noticeable bleeding on tp when I wiped. Had a gut feeling it was a misscarriage my hcg levels where 160 very low for being 6 weeks the dr. Told me he was 85% sure it was a misscarriage not very reassuring but bleeding has increased and I'm having blood clots. Just wondering how long would the process take and my body would go back to normal?
