I had it a couple of years ago and I loved that it was hormone free, so it didn't mess with my natural 25 day cycle. It was rough going in, but I haven't had children and I did it on a whim at the doctors office and I could have taken pain meds before hand or something to dilate my cervix a bit (that was the previous plan but I chickened out), I had a couple weeks of cramping and spotting afterwards but after those two weeks everything was good. I'm pregnant now and plan on going back to that after the baby is born.

I loved it.It did give me bad cramps, which I'd never had before. So I got a heating pad.It also made my period last a bit longer, and my flow quite a bit heavier. I found that using a cup instead of tampons helped... less expense, less frequent bathroom trips.It had its inconveniences, but being hormone free was such a huge plus, since any kind of hormonal BC has always made me depressed and self-hating.  I'd use paraguard again.

I had the Mirena. My cycles remained normal as far as timing but became more painful. I'd experience heavy cramping & as time went on the cramping only got worse. Also after having it removed I had 3 miscarriages in 18mos. For a while there I didn't  think we'd have any more children.
