Since those with PCOS do not ovulate regularly getting pregnant can be tricky. There are a number of medications that can take you to ovulate more regularly. Clomid is the most common medication to get your ovaries ready to cooperate with ovulation and pregnancy. Clomid is given to help you ovulate regularly making the egg available to become fertilized. If Clomid fails, Metformin and gonadotrophins are next on deck to get your ovaries working properly.
