"i had the implanon implanted aug 3, 2011. i was diagnosed with polycystic ovarian syndrome in 2006 and was put on a estrogen birth control until i switched to the implanon. i have gained at least 20 lbs, feel tired all the time and have no sex drive. i&#039;m cranky almost all the time where i used to be easy to get along with. the pcos symptoms such as unwanted facial hair seems to have gotten worse since i started implanon. i had a 7 day period at the end of aug(2011), bled one day at the end of sept(2011), 3 day period in the middle of oct(2011), 4 day period the middle of january(2012) then bled 2 days the following week, and bled 1 day the second week in aug (2012). the random days i have bled wearing a panty liner sufficed."
