birth control
"Its been 5 months since I got the implant and I have already gained more than 15 pounds. The first 2 months was constantly having headache which I never had before and soreness in my breast. I have mood swings. Sometimes I snap for no reason. Definitely easily irritated. 
My sex libido also decreased. 
The only good thing about this birth control is that you don't get your period anymore. A little spotting but not bleeding. I'm taking it out for sure."
