Losing more than 20-30 lbs

V • After 14 months of struggle, had baby girl in 10/2015! So blessed...
Hi all, I thought I would start a discussion for those who have more than 20lbs to lose. My BMI is 36 and I'm worried it's affecting my fertility (TTC #1) as I've had 39 day cycles since stopping BC when I previously had 28 day cycles at a lower weight. My kryptonite is cookies. :) I started weight watchers and trying to drink lemon + water in the mornings. My DH and I have started working out. Any suggestions, commiseration, or success stories would be great.
