I've had it since August 2009. No issues so far. Expect alot of bleeding when you initially get it. Since i've had it i've experienced 0 cramps when AF is in town.
Eh, I had it, and it embedded into my uterine wall. It also made me into a raging bitch and made me gain weight that I still can't really get worked off. I'd never get another one.
After I had Dd in 08 I got the Mirena. The first year I had it, it was great. Lighter shorter periods, no cramping etc. The only issue I had was Dh could feel the string so my Dr cut them back.
Then I started having cramps and irregular periods. Eventually I would bleed 2 weeks stop a week, bleed a week, stop for two months etc. Anyway I went to the doctor and the Mirena had embedded in my uterus.
I had it removed in 2011 and started TTC. In July of 2012 I got pregnant and had a miscarriage with complications that we believe to be due to the Mirena.
Eta: I also had some weight gain, mood swings and I completely lost my sex drive.
I had it for 4 years, took it out when we were wanting to ttc, waited 2 cycles to let my cycles build (the last 2 years on Mirena my cycles were either nonexistentent or very light) and we got a BFP the first cycle we actually started TTC. If we were wanting to wait a while before the next baby I'd definitely get it again but were wantin to have another after this one as soon as my body is ready again.
