Ttc with pcos need advice

Kelli
Hi ladies my hubby and I are ttc for the past2 years. I have been insulin resistant and did metformin for a year and nothing so I resorted to losing weight I went from 250lbs I'm currently down to 196lbs from March 2015 to now. Well anyways I'm still losing weight but my doctor says my lh level is still way to high. My fsh level is considered perfect. He put me back on metformin and I was wanting to know what else could I take to help in getting pregnant. Also I'm taking prenatal as Well
