TTC with PCOS, need some help ladies?

I was diagnosed with PCOS about a year ago, and about 4 months ago we decided to TTC. I had no idea how much PCOS affected my body, and now after trying for four months with no luck I am looking to change my lifestyle in hopes to conceive naturally. I want to cut out bread, pasta, almost all refined carbs. I know eating eggs, meats, veggies, fruits are all good. I am also overweight, 5'5 and 185...I hear losing 10 lbs would also do wonders and some women that is all it takes and they get pregnant. I want to know from ladies with PCOS if you did these things and then got pregnant? Any other things I can do to help try to conceive sooner and naturally?
