The IUD coil

Aime
So I have had my cool just over 2 years now and although there are a few things I would like to change I would highly rr come d anyone currently on the pill to change over. I was gaining so much weight on the pill it was silly. Since changing without dieting or exercise I have lost over 5 stone in 2 years. 
The only thing in my life to change was my birth control.
