TTC w/ PCOS..

First off let me start off with that I have pcos. Was diagnosed about 4 years ago. Have tried lots of different things. None which worked or just made me sick. For the last six months I have been working on my health and trying to reduce the pcos symptoms. Loosing weight (25 lbs so far), eating healthier ( no fast food or soda in six months), trying to get my periods regular. I have been feeling so much better!!! Except for still not getting pregnant. My husband and I have been trying for about 5 Years... any suggestions would be appreciated.
