"i had the mirena placed november 14&#039;. i am 23 with no kids and the insertion was probably the worst pain i&#039;ve ever experienced. the pinch you feel is the absolute worst ! after the procedure i cramped a lot . the cramps were so bad i couldn&#039;t walk but that only went on for a week. after that no more cramps and everything went back to normal . in january of 15&#039; i started spotting almost everyday of that month. i assume it was because my body was still trying to adapt to it. it is now march 16&#039; and all i&#039;ve had is weight gain and i mean i am 80 pounds heavier since having the mirena. it does its job and i&#039;ve had no pregnancies but the weight gain is terrible"
