Losing weight to try and conceive with PCOS?

Hi all

i am totally new to this, I have just came across this page and read some interesting stories. I am 20, 21 in a couple of weeks me and partner would like to try for a baby however after being diagnosed with PCOS a month a go I can't say it has given me much "hope" of being able to do this naturally - from my research anyway.

I know that losing weight and a healthy diet is the way forward but how do you get yourself motivated and on track to lose the weight I would say I am a couple of stone overweight and I really want this for the both of us but why is it so difficult!?

any pointers please please please fire away, just a chubby bunny looking for some advice?

Thanks
