Nexplanon!

Alanna
This is the birth control that gets inserted into your arm(bicep area)💪🏼 it's suppose to last 3 years. They say it takes up to a year for your body to get in sync to it. Then you're  not suppose to have your periods for the remaining time...👍🏼Now here's my story..
I've been on some form of birth control basically since I started getting my periods, because of extremely bad cramps and mood swings exct. Eventually I got sick of taking pills every day or refilling a prescription every couple of months so I got this nexplanon bc. 
I've had it for 9 months. Right now I'm experiencing my 3rd 21 + day period....!!!!! Which includes mood swings( I'm told I'm horrible to be around ) awful cramps, nausea fatigue, light headedness, and really I just feeling like crap for like a solid month.. NOT FUN! 
So here's my question! Do I get it out and give my body a break from all the hormones ?or wait it out another 3 months to see if what "they say" is true ? Please help me out guys I need opinions of people other than my mother who doesn't like any birth control! And my boyfriend just wants me to be happy and healthy so it's really up to me.. 😘thanks
