Period problems

Michaela

Ok so recently I was diagnosed with hypothyroidism. But I've noticed my periods come like clock work but they are so stupid heavy and painful. I can soak through a super heavy night pad a cheap maturity pad and a super tampon in just shy of an hour. I get dizzy nausea exhausted blurry vision disoriented and confused and I'm constantly freezing. I drink 2.5 24oz contigos of water and eat pretty healthy. I'm a breast feeding mom and my supply literally disappears for the 5-10 I bleed for. I clot. The smallest I've had was the size of my thumb and five largest the size of my hand stretched open. I've seen the dr but I'm apparently in perfect happart from hypothyroidism. What do I do. I still have a fee blood tests.
