"i am a 24 year old mother of 1. i&#039;ve had my mirena for about for 3 yrs and 6 months. insertion was a little painful just a few minor cramps then i was fine right after. i bled for 3 months straight after but my period only came back every 3-4 months after that. during the second year i still spotted every 3-4 months but no major bleeding. my period has yet to stop altogether but the spotting does not bother me just the irregularity of it. i have experienced slight hair loss and weight gain. but my biggest problem would be the bacteria infections. i never experienced them until after i had mirena. my doctors said its just my body&#039;s way to react to it. i get about 4-6 a year but besides those side effects i have not been pregnant."
