"worst birth control i have been on. i got it  1 and 1/2 yrs ago. first 7 months was fine, then i started bleeding randomly. i bleed on average 25 days out of a month (most days straight was 22) those 6 days i don&#039;t are mixed in the middle mostly two days at a time,  some even include spotting which i don&#039;t refer to as bleeding anymore. i live with a tampon in! had my hormones and thyroid checked for to see if that was the culprit and had a transvaginal ultrasound which showed i had a cyst on my left ovary. it definitely will keep you from getting pregnant due to the constant bleeding. i&#039;m getting mine out at 10:20 tomorrow and i can&#039;t wait ( have thought about cutting it out myself ) i don&#039;t want to wait 12 hours!"
