I have recently being diagnosed with severe anaemia, I had 3 pints of blood to try help... This was due to heavy periods. I was prescribed nothisterone and put some weight on. I came off this and lost weight. Since June I have lost 15kgs. I have developed other symptoms and wonder if this is a result of nothisterone. Hair loss, beating heart, blurred vision, regular bowl movement... Sweats, do you think this old be overactive thyroid
