"i&#039;ve had my iud for almost 6 months now. i researched a lot about birth control before picking the mirena. in the beginning, after having it in, it is a rough ride. bad cramping, bleeding for a month straight. once that stops and ur body  adjusts, it&#039;s pretty nice to not have to think about birth control. i still pms, get cramps, and have spotting around the time i would be having my period but not anything like how it was naturally. i have concerns about long term affects bc i&#039;m only 21 and i would love to have babies one day, just not right now. bc iud are so new they are still working out long term affects so i would only suggest getting one if you are done having kids."
