I went off the thyroid med for awhile, and sure enough, massive bleed out. I am totally trapped taking the drug. Even though I don't feel I need it as often as I used to. But not taking it, I get severe, really, really severe heavy periods worse than if I got stabbed in an artery. When I regularly take levothyroxine, my periods are normal to light and sometimes I barely get them. Go off it, and scary bleeding. I talked to my doctor about this, and she was like, you can a "procedure" or surgery or take more hormones and possibly get cancer or a blood clot or stroke. Or just stay on the lev. Great choices. As I've been bleeding out badly for 48 hours and more now, I caved and took the lev. There's alot of literature out there on thyroid disease and heavy bleeding. Unfortunately, it is a symptom of Hashimoto's and Hypothyroidism if you do not treat it. And as I don't want to be chopped up, do a procedure, or take more scary things, I think I'm stuck with the lev. And I already have side effects from it. The levothyroxine is the cause of my acid reflux. So that's right here now. It's given me a headache. I feel like crap on it. It also messes with my joints. But if it keeps the periods regular or at least lighter, I'll take the monster pill. I'm just so sick of suffering with stuff. And now I have to pray the heavy bleeding subsides on its own. It's so bad that I can't go anywhere. I hate this. I haven't had this in a few years. I only had it before I took the lev and wasn't treating the Hashimotos. After I started with the lev, I didn't get it like that again for years.
