birth control
"I had Skyla inserted a little over a year ago. The insertion itself wasn't too painful, but I did have bad cramps for the rest of the day after insertion. However, I no longer get cramps with each period. My periods are WAY lighter than they were pre-IUD. The one thing I've noticed that I don't like is that I'll think my period is over, but a couple days later it'll sneak attack and come back out of nowhere (though so light that I only need a thin pantyliner). I've gained about 8lbs since I had Skyla put in, but also have a job change where I went from walking all day to a desk job so I don't know if there is a direct correlation, just thought I'd mention."
