Anak, this is something you really need to check with your OB right away, kahit na sabi nila complete, ang ongoing bleeding at pain deserve a follow-up visit or call, hindi ka dapat mag-alala mag-bother sa doctor nila. They need to see kung normal pa lang yan or may kailangan pang i-address.
I know how scary and painful it is, and I'm so sorry you're going through this. Every body heals differently after a miscarriage, some have spotting for weeks, some cramping, pero kasi ikaw may clots pa rin, mejor talaga pag-usapan with your OB whether kailangan monitoring or anything else. Wag mag-hesitate to call them anytime, lalo na kung tumataas pain or bleeding.
Hang in there, and take care of yourself.
