"the procedure feels like a pap smear + 3 intense cramps (nothing worse than bad period cramps). then it&#039;s done! i felt a little uncomfortable for 1.5 days and i was back to work on monday. i had spotting for about 2-3 weeks after the procedure. i spotted during my normal period week for the next 5-6 months, but very light and not like a full on period at all. i have now stopped getting my period all together but i experience just 1 pms symptom when i&#039;d normally have my period-- not cramps or moodiness, just sore breasts. i&#039;ve lost 10 lbs. since having the mirena put in. best decision ever! took a while to adjust to the lower dose of hormones, but no more expensive pills/forgetting to take my pill/periods/moodiness from high-dose hormones."
