birth control
"Well, I just got the Mirena March 20, 2015. The insertion hurt so bad (I guess its because I have no kids). I'm 18 and right afterwards I began to bleed. I bleed off and on for three days and now, March 26, I'm having light bleeding. I came on my period three days ago and had terrible cramps. From the look of it though, I may be bleeding for 2-3 months. I just hopes it gets better! Thank you all!"
