"so i&#039;ve actually had this implant since i&#039;ve been 15, and i&#039;m by 18. when i first had it put in, i bled and spotted for 6 months, which i was warned would happen. after that my cycle was very irregular, either every couple weeks or couple months or even 4-5 months without. it is sometimes worrying going so long without one, because i always wonder if there&#039;s something else wrong. but i have to say i love the implant, it&#039;s super effective. i get no cramps or mood swings and my cycles are very light and last 2-4 days at most.  i would definitely recommend this."
