BIrth control

Short rant I guess I'm on the mirena for birth control and I swear why do I always get the rarer side effects? Only 5% have weight gain... yeah I feel huge after getting this darn thing. Same with skin irritation... can't stop itching and of course they say for most women they have lighter shorter periods but in a very small percent it can be longer and heavier... well of course that would be me! Ive been in debate about calling my doctor and seeing if I can get on something else because this isn't working, but then I remember I've never done well on any of it. it all makes me feel like shit. They all cause me to gain weight and in some cases increase depression *sigh*.
