I am 20 year old female and i'm extremely skinny and i'm suffering from pcos for the last 5 years. I was put in birth control pills diane-35 but I stopped taking them after 1 year because I always felt nauseous and dizzy. Now I suffer from extreme period pain sometimes causing me to vomit. I also have very irregular cycle and once my period starts it continues for a month sometimes 4-5 months. I now take trapic mf and meftal spas. My recent ultrasound report shows my right ovary is twice the normal size. I also have low blood pressure of 90/60 I want to gain weight and increase stamina please help.
