"i&#039;ve had kyleena in for about 5 months now. the insertion felt like a pinch and then mild period cramping, but when i returned home i had the most serious cramping i&#039;d ever had the rest of the night. i took three 200mg ibuprofen beforehand. i bled lightly for about 4-5 weeks after the insertion and since then i&#039;ve only had one period that lasted 7 days and was pretty light majority of the time. compared to my birth control pills: cons: my cramping is worse, my period is longer, recently have been breaking out consistently pros: no pill to take every night, 5 years of birth control, sex drive has returned"
