"i&#039;m 24 years old and this is my second time to have the mirena. i had it the first time for 5 years then had it taken out due to the 5 year period and got put on the pill. the pill was not for me at all. so i decided to get the mirena again. i do not have a child. the mirena did hurt when i got it put in and did have bad cramping and some spotting but it was no unbearable. i was fine the next day. i have no gained weight being on the mirena or have had trouble with it. i still sometimes spot and my period is not regular anymore but that comes with it. i personally believe if you are not ready or do not want to have a child right now the mirena is the best thing!"
