"i recieved the implanon birth control in october of 2014. i am absolutely terrible at remembering a daily pill, so i&#039;m that aspect, this birth control is great. i haven&#039;t gotten pregnant and i have unprotected sex (sorry if tmi, but this thing really does work) so for the first few months this was amazing. then i started noticing myself become upset incredibly easy, like sobbing over small things. i also noticed i would become angry for no reason, and my boyfriend noticed this also . i bleed randomly (not heavy) and cramped worse than before i had the birth control put in. i&#039;ve gained a fair amount of weight (15  pounds) and it seems to keep coming. overall, it&#039;s worth trying, but i will not be keeping mine."
