birth control
"I give this a 10 because it has been very effective in preventing pregnancy. I got mine in June 2017 so I've had this for 1 year. During insertion I felt a pinch that lasted a few seconds. I did not bleed at all. I was told it was common to bleed 3 to 6 weeks after. I did not bleed until my next scheduled period. It was a day or so off. It was a light flow so it lasted a few days longer. Spotting for a few day then a light flow in the middle and finished spotting. I never needed a tampon or a regular pad. I only wore thick liners. I did however experience side effects. For the first few months I had headaches every other day. Then right before my period I would get sharp cramps that lasted a day then normal cramps and pain. So far I love it."
