"this is my second time with the mirena. the first time was after my son and once the 5 yrs was up i got it replaced with a new one. my first mirena was wonderful.(no heavy bleeding, not getting pregnant etc) i dont know if they changed something in the birth control.my 2nd mirena i have had massive side effects.( nausea, vomiting, mood swings, weight gain, 0 sex drive, abdominal cramps) this is insane i talked to my doctor as i was vomiting w/nausea for three days off and on. he explained that there could be a problem with the birth control and that i should come in asap. long and behold i had an ectopic pregnancy and was given the pill to stop my pregnancy. my iud was removed after this and i&#039;ve not looked back"
