birth control
"I have had Mirena for a little over a month now, and so far its been great! The insertion was very painful... much worse than people said, but this varies between people. I had severe cramps for a few hours after it was inserted, but after that they were mild for the rest of the day (and the next). I spotted for a few days, but that went away and there was nothing until my period. My period was lighter, but it lasted longer. It was basically spotting (slightly heavier than a pantyliner could handle), for seven days. Since then, I've had some sporadic light spotting, but its definitely manageable. As for other side effects, I haven't noticed any weight gain, mood swings, or a noticeable increase in acne, and I am prone to breakouts."
