"nearing my 3 year mark .  and i can not wait to have this thing taken out. the insertion process wasn&#039;t bad at all, the bruise was pretty nasty but that&#039;s it. since getting the birth control implant i&#039;ve gained about 20 pounds, i have crazy cravings, and the mood swings are the absolute worst. my periods are irregular i get a period every 2-3 months and it&#039;s always on the regular to lighter side but it always lasts 7 days or more like a constant spotting almost. the only thing that&#039;s good about this birth control and it&#039;s the main reason i&#039;ve kept it is because it&#039;s effective."
