birth control
"I got Nexplanon back in February and at first I was very emotional.  Was sad about everything.  But it lasted only a month.  After that, I spotted a couple times but nothing heavy, painful or long-lasting.  During that time I also got bad acne on my face which I never had a problem with before.  That was the most embarassing part and lasted a few months.  I called my doctor and they told me to stick it out because side-effects should calm down at the 6 month mark.  I also gained about 15 pounds but that was ok with me because I am super skinny and needed it!  So for about 3 months now, it's been great!  No mood swings, no cramps, no period, acne cleared up.  Just remember it reacts to everyone differently."
