"i had skyla inserted october 2014, it is now february 2016. i am 29 years old and have been on birth control since i was 21.  i have tried several different varieties of the pill as well as nuevo ring. in search of the perfect birth control i think skyla comes close, but not perfect. there a couple cons to this birth control, but in my opinion the pros definitely out weigh the cons.
pro: free- completely covered by my insurance. 
pro: almost worry free. i was told to check the strings every month to make sure the iud is still in place. so far so good. 
con: when i switched to skyla my menstrual cramps returned after almost 9 years. they are not as bad as i remember and after a heating pad and advil i am fine. 
con: irregular period"
