Hormones after quitting the pill

Dodo
I was put on the pill in addition to metformin for PCOS. I also take medicine for hypothyroidism. About 3 months ago I stopped taking my birth control in order to have my cycles regulated naturally and get ready to try for a baby this December. My hormones have been all over the place...I'm always tired, some days I can't get enough carbs, and other days I can't get enough water. I'm not that moody, but there are times where I just need a good cry. I have gained some weight since being off the pill. My diet is clean and gluten/dairy free due to food allergies. I've tried exercising and yoga, but I can't seem to stay motivated...all I want to do is sleep. I was just wondering if someone else has had similar experiences and if they have any advice to give about getting back into the swing of things??
