No periods for straight 6 months. And when it comes it's extremely painful and heavy bleeding and lasts for many months continuously everyday. After ultrasound no pcos traces or cystic ovaries were found. Also my Prolactin level is 17.36 And  T3 is 3.46   T4 is 0.95   TSH is 3.89 I'm having this problem from past 3 years. And as this problem has been started I have gained too much weight also. Continuous workout is also not possible in such conditions. I don't know what should I do now. Please suggest me some cure.
