You cannot get pregnant if you have an intact hymen and are not having coitus. As for the PCOS, you will need to take the Diane till the menses are regular, and you also need to lose weight. Chances for pregnancy are even better if you take ovulation inducing drugs, but for that you have to plan to be with the husband and follow up with a infertility specialist for monitoring egg formation as well as ovulation timing by ultrasound scanning.
