"other than being effective in preventing pregnancy, the side effects i experienced with the mirena were not enjoyable. i really liked the idea that it was a local hormone as opposed to a systemic hormone (only puts the hormones into your reproductive organs instead of throughout the entire body which is what the pill did), and the convenience of not having to take a pill every day was the biggest positive! however, due to the hormones being local, i noticed the positive benefits i experience with the pill such as not getting acne, came back. my skin got really bad. also, i ended up getting my period more frequently, for longer periods, as well as had spotting in between periods for the entire 2 years of having my iud i got it removed."
