I've been told that I'm not ovulating...doc has advised me to gain at least a stone in weight to see if that will work. I'm about 7st and I've always been this slim, Ive never weighed more than 7 and a half! Ive got a 8yr old DS and would love a sibling for him. I haven't been pregnant since I had my DS but I've only been trying the last 2years. Has anyone else had to gain/lose weight to try and get the body ovulating again? If so did it work? Are there any happy stories out there? I can't stand the thought of not being able to conceive naturally! Also anyone have any idea on how to gain weight? I eat loads and drink calorie shakes in between meals. I'm naturally skinny, it is a curse....
