Every single birth control i have been on has  'weight gain' side effects. My bestie was on the ssme as me and she put on 15kgs, which she has since shed, but damn. Somehow though, i manage to stay classed as underweight. My mother if a fricken planet, muh cundishuns and all, yet somehow, i know to eat relatively healthy and not to over dramatize every single little thing to justify my small weight. I know i could stand to out a few on, and when my toddler stops demanding i carry her everywhere, im sure i will reach an healthier weight, without turning into an orge.  The never ending excuses baffled me!
