Very heavy bleeding/clotting during first real period post-removal

First, please forgive me if I get the exact time periods wrong as these experiences are beginning to run together. I waited 75 days post-removal for my first REAL period. Now I'm on my 16-18th day of an extremely heavy period. I've had clotting on and off which didn't concern me much as I read a bunch about that here. Today I passed a clot larger than a golf ball and the cramping and bleeding only seems to be getting worse (or at least steadily heavy). I'm starting to feel other things, but at this point are not sure if they are physical or anxiety-related. I understand that my body needs to flush out after 2+ years of not having a period, but at what point to I react instead of just wait? Any ideas? Thank you!
