I have PCOS since 16 and I am 20 years old now. I didn't do anything to deal with this problem or anything. Just took pills for 4 months every year to have periods. But now after I have done research on PCOS, I have heard that if PCOS is not treated asap, it will leave a long term effect of infertility and I don't want that. As it has been 4 years I have PCOS and I haven't done anything specifically (such as losing weight, exercise) would it be too late now and will I have this long term effect of infertility.
