I have been trying to get pregnant for three years, i have pcos&metabolic syndrome. myperiods very irregular. what steps can i take to get pregnant?

Get help: You need to see a doctor, it often turns out to be easy to get pregnant with a little professional help. If you've been working with a doctor for 3 years without success, get a new one. You don't say, but if you are overweight then even modest weight-loss can help, possibly even just trying at home.

See an RE!: Board certified reproductive endocrinologists specialize in treating pcos. Consider seeing one who is an expert in the modern treatment of pcos to assure you're on the proper track.
