birth control
"This summer - July of 2015 - will be exactly 5th year as I've had my mirena. I had it inserted 3 months after having my 2nd child and it took no more than 10 min for my Dr to do it. 
I loved having mirena for 5 years as I didn't have to worry about birth control at all! 
The only minus is that for first year or two I had irregular bleeding or to be correct spotting.  It wasn't really a period but every couple of weeks I'd have to use slim daily pads for couple of days at a time. Still, it is much much better than having regular painful periods and to worry about birth control every day. 

So, I'm having my removed in a month and probably will give my uterus a rest for 2-3 month (if it's necessary I don't know... Maybe not) and get another one."
