Hi, in pcos patients, the problem is with ovulation and thus periods are irregular. So, you might not have ovulated this month and thus periods got delayed. You can take some progesterone like deviry or meprate for inducing periods. You can take some medicines like clomiphene or letroz for ovulation. You can track your ovulation by repeated ultrasound. When follicles reach a size more than 17 to 18 mm, take injection for rupturing the follicles. Be in contact with your husband for 2 to 3 days after injection. Take progesterone for next 2 weeks. Do a urine pregnancy test at home after that. Only progynova will not help much. It is given when endometrial thickness is less. You can try like that for 3 to 6 months.
