birth control
"Here's the run down of my experience with nexplanon. Have had it a couple months shy of a year. 

Month one- this is great, haven't had any side effects, can't even tell this thing is in my arm. 

Month 2- k theres some spotting throughout the month, but I was warned that might be a side effect and didn't have my period the first month, still okay though. 

Every month after that- ok I've made several trips to Victoria secret/pink spending hundreds of dollars because all my underwear have been ruined. If you think you have a safe day where you can wear cute panties, YOU DON'T. Pretty sure I'm gonna need a blood transfusion soon. My mood is fine one minute, the next I don't want to be touched, talked to, or even looked at. DON'T GET THIS."
