Uggghhhhh

So a few months back i had he paragard iud put in. I know it is non hormonal so i didnt think id experience anything like this. The first half of my cycle i HATE food barely get in 500 calories a day. Cant force my self to eat and am totally turned off by everything. Then i get close to my period and feel like a bottomless pit can not stop eating feel starved no matter what i eat. Ive been trying to lose weight. I was down to 215 im back up to 230!!!!!! Super depressed about it and idk what to do. I do work out every day but i know the eating is a huge problem. So frustrated
