... thyroid symptoms and my blood work was within normal range. Over the past several months I have gained 20 lbs. rather quickly, hair is falling out, fatigue, heart rate is lower and I last weekend I spotted for 3 days (I haven't had menstual cycles for 2 years since I went through the change of life), I'm also more agitated which is not in my nature. My blood work revealed 0.874 which is in the range, however my last reading was 1.470. I don't feel like myself and I'm concerned and need more advice
