birth control
"I have had the Nexplanon in for 9 months . Getting it inserted was not painful but a good hard pinch.  I bruised afterwards for about 4 days and was sore for about 4 weeks . I had read the reviews on the menstrual cycle being light or not having one. But my own experience, I have a cycle once a month and then about 4 to 5 days later a heavier cycle which last about 3 to 5 days.  I dont mind it because I don't want kids as if now and its good for 3 years. Which is a money saver if you have insurance."
