birth control
"I just had my second Nexplanon inserted in August 2016. Overall it's been great. When I got the first one done I only got my period about every 3 months, but it became more regular in the third year. Now with the second one inserted, my period hasn't shown up yet and probably won't for a few months. The only negative side effects I have experienced are some minor weight gain (although I have experienced weight gain on every birth control I've tried) and considerable breast pain a few days before I start my period."
