So here I am again with yet another question!!! This time it's a ladies problem! I was diagnosed with hypo in May and have been taking 100mg levothyroxin since then. I have had various problems along the way and have discovered I have a severe iron and vit D deficiency so am therefore now on iron tablets and vit d tablets prescribed by the doctor. I have been taking these since end of October. I came on November 28th and ever since I have been bleeding. It is only light now but it's there. It's very red blood and slightly clotted. Obviously with an iron deficiency, this something I don't need!! Does anyone else have period problems? I do have a small fibroid and wondered if it was merely that or if it thyroid related??
