"i am 26, and had the mirena placed at my 6 week postpartum check up after having our second baby girl. all that happened was i felt very mild, barely noticeable cramping that day, and on and off randomly since. i have a higher sex drive, no acne (which is wonderful because i&#039;ve had problems with adult acne), hand lost 5 pounds that week, and now am steadily losing weight. nothing is being or has been negatively affected. i know everyone is different, i was an excellent candidate for it because of very heavy, long lasting, and painful periods.
