i have never used the mirena - but i have good reasons not to. my cousin had some horrible issues with it. i mean terrible. but then again, everyone is different when it comes to these sorts of things. so it may work for you?
It may not work many people end up pregnant.
I had mine in for 2 years and hated every day of it I would cramp all month and sometimes have 2 periods a month and it was painful during sex and just a horrible experience I got it taken out nov 5th and 15 days later got pregnant I would not recommend it. I would go with the shot!
I cant go on the shot because it took me 5 yr to get preganat, after i stopped taking the shot.. I had to have some really uncomfortable test done to see if i was able to become preganant..
I had it for 4 years, no issues light periods were nice, I had mine removed in jan in mid of my cycle so my first period was light and I got pregnant but lost my angel last week. It wasn't because of mirena because the doctor told me my lining was thicken and normal for my pregnancy stage. Once I get pregnant and deliver my baby I am etheir getting paraguard the copper or mirena again. Some people have issues some don't. Good luck
