"i have used the mirena as it seems to be the most consistent release of hormones, therefor helping mood swings, acne, weight gain etc. i just had 1 removed and another placed. never had children, and my cervix &quot;falls to the floor&quot; and to a side, so it&#039;s a bit more uncomfortable than some women. but, nothing that extra water and advil cant soothe. it is def worth 1 day of uncomfortable for 5 years of relief lol. my periods mostly stopped basically was spotting for a day or two after year 1. prior to year 1, still light but lasted a day or so longer. my strings to the first got &quot;lost&quot; so dr. (highly recommend an ob/gyn)  used ultrasound to locate and and get it before replacing it. so, a few negatives but well worth it!"
