"i am 21, 1 child, had mirena for a year. overall satisfied, initial insertion uncomfortable but fine after that night. if i have a period at all it is very light spotting for 1-3 days maximum...first time having sex he said he could feel it but no more after that. i am experiencing period sypmtoms without the period that i&#039;ve never had before. ex: cramps, cravings, increased appetite... which led to a light weight gain but like 5-7 lbs nothing i can&#039;t get back under control."
