birth control
"Worst experience ever.I got my nexplanon in January of 2015. Insertion was alright, it bruised pretty bad and always itched. I was under the impression I would not have a period at all, but the exact opposite occurred. I have had off and on periods that typically last about a month. Being in the military and on a deployment I didn't want to have to worry about my period, but oh boy I did. Mood swings like crazy. One second I was alright and loved the world and then the next I was yelling at my boyfriend for the smallest things and wanting to cry. I was on the pill previously and did not experience anything like that. 
I got it removed earlier today and it was a wave of relief. Finally I know I will have regular periods!!"
