I am 22 Years old weighing 34 kgs and height 4'10" I have pcos detected from 5 years. I have very irregular periods. Last month my periods continued for a month with heavy bleeding. After taking one regestrone as directed by my doctor, periods stopped. Now after 15 days on regestrone I again had periods which lasted for 5 days. I had cramps and pain so doctor suggested blood test. They tested LH, FSH and Serum prolactin while I was on my periods. LH levels were 3.88mIU/ml FSH levels were 2.82mIU/ml and prolactin levels were 24.16 ng/ml. Due to high prolactin levels doctor gave me caberlin for a month once a week. Why are my prolactin levels so high? Am I pregnant? Is there any serious issue of tumour in hypothalamus? Do I need to worry and take serious measures? Help me.
