"i have had mirena for a month now. i switch to mirena because i has absolutely no sex drive on the pill! the insertion was pretty painful (probably like an 8 out of 10) and the cramping has been bad at times, but not always. i also spotted for like 4 days after the insertion. since having mirena, my sex drive is back to normal and period was very light! only required a light tampon at the max but for the most part just a panty liner which is awesome! i would recommend this to anyone who wants an easy form of birth control or for anyone who wants their sex drive back."
