Hi doctor. I am 18 year old. From 5 months I did not had my periods. Last time in feb I got that. I am really tensed about that. My mom told when she was in my age she too had irregular periods but after few months it became regular. I am afraid of getting pcos. Earlier I had back and arm acne so I got nervous that might it lead to pcod. But now that are totally cured without any medici e. I do not have acne now. My skin is oiky might that can be reason. I am afraid of going to doc because I myself feel by reading various symptoms of pcos. I am obese also. I have started exercise for that nd started doing yoga. I am afraid it might cause infertility in future and might I cannot become pregnant. Please help me. I do not want to go to doc. Will loosing weight bring back.
