[HELP] I just got engaged and need to lose as much weight/inches as I can before October 2012!

Hello everyone! I've recently gotten engaged(yay!) and I'd like to lose as much weight or as many inches as I can by my wedding in October 2012.

I have always been on the heavier side. I'm 23 years old female and I was diagnosed with Polycystic Ovary Syndrome when I was 17. So, I have been on "the pill" since then and it has the wonderful side effect of weight gain and PCOS itself makes it difficult to lose weight. I'm really just looking for anyone that has any advice for types of exercise or diet tips they can give me in general or for PCOS sufferers.

I don't have a picture of myself to post at the moment, so here are some stats. Current weight: 207 lbs Height: 5'3" Bust: 43 inches Underbust: 37 inches Natural Waist (skinniest part of my torso): 36 inches Waist (at bellybutton): 40 inches Hips/butt: 46 inches Upper arm: 14 inches Thigh: 26 inches Calf: 16.5 inches

Like I said, I'd like to lose as many pounds and/or inches I can by next October. So far, my plans are to try to cook for myself more rather than relying on frozen meals and to exercise more. I'm going tomorrow to join my local Planet Fitness gym. I'm not sure of any specific exercises that would be good for me to do. Recipes are also very welcome. Anything that you guys could think to help me. Thanks! ^^
