"i used to have very, very heavy periods and very painful cramps. it&#039;s been 8 months since my last period! they stopped 4 months after mirena was implanted and i can&#039;t express enough how much i love it! i&#039;ll admit, i&#039;ve never been pregnant so it hurt when the doctor put it in, but that pain lasted a minute at most so it was completely worth it. i recommend it to every lady. it is the most effective form of birth control, you don&#039;t have to worry about taking a pill every day or getting a shot every 3 months. i&#039;d get it even if i wasn&#039;t sexually active. best of all, i got it for free at planned parenthood! if you don&#039;t think you can afford it or if your insurance doesn&#039;t cover it, get an appointment with planned parenthood and see how they can help. it is great."
