"i have had this bc since  2011. i am now 24 and going on 6 years. i am considering a 3rd implant. i will admit in the beginning both times was horrific. i was on my period on and off for roughly 3-4months. it was not heavy just frequent. when i first got the bc i did experience dryness and an infection from over using tampons because i was unsure of what was happening. 3 month long periods are no fun. within a year my periods came regularly but last from 10-16 days every time. this is an undesirable side effect; but still no pregnancy.  i do not have to remember to take a medication daily, or weekly. i recommend trying for 1 year and being open to discuss with sexual partner. their reaction does influence the effectiveness of this bc."
