Hi, I am a 26yo female, 105lbs and 5 3 . My dad has hashimotos and I have wondered if I have some sort of thyroid issue going on. I have heavy periods (around 70mls on day one, total period usually around 130mls). I am typically unable to leave home on the first day of my period due to feeling so weak. I have low blood pressure, around 94/60. I am almost always very cold after eating meals, and experience extreme fatigue before bowel movements maybe once/week. No issue with BM, just the fatigue beforehand is debilitating. I have all my energy back after going. My doctor has tested my TSH level a few months ago and it came back within the normal range (0.742 uIU/mL). Any suggestions?
