"i got the nexolanon implant in september 2015, yet i&#039;m still having side effects. my periods are incredibly irregular, either having them one after the other immediately or not having any at all for at least 4 months. when i do get my periods, they&#039;re either extremely heavy or barely even there. the cramps i get are unbearable, so if anyone wanted nexplanon.... don&#039;t even bother thinking about it."
