When you are trying to conceive, there may be lot of stress, stress releases adrenaline, free radical damage to the egg, and that is the main reason for infertility. I have seen many cases who try for baby won't get
pregnant. when they stop trying, they get pregnant. And physical activity also plays a definite role. You didn't mention about ur weight, BMI. Wt loss is important in pcod patients.Plz go to gym, do meditation, have enough sleep.. Don't be under stress.
