"21 years old and no kids. approx 120 lbs. i got kyleena inserted about 12 days ago. i was originally taking the depo shot but i wanted something more long term. i&#039;ve had mild to severe cramps for my periods my whole life. during the insertion i experienced what felt like 2 of the worst period cramps i could ever have (i screamed). once it was over i was fine, but i did have severe cramping for hours after until the medicine they gave me finally kicked in. i was taking ibuprofen for about a week because i was still experiencing cramping. my period started going away and was very light. my doctor prescribed me estradiol 1 mg to help with adjusting to the iud. i&#039;ve been taking them for about a week. starting yesterday my period became very heavy."
