Losing weight just to gain it back...LOL

Options
Hi all. I'm new to the site, but I like it so far. Just started today. I have 80-85lbs to lose. The hubby and I are ready to have another baby, which would be #2 for me and #1 for him, but I have gained so much weight that my system has stopped working. So, of course, no ovulation=no baby. :-( At this point, my ob/gyn can't find a thing wrong with me other than my weight throwing off my hormones, and has diagnosed me with PCOS (polycystic ovarian syndrome). So, following her advice, I'm trying to get back down to a healthy weight not only for myself, but so we can have another baby and a healthier pregnancy!
