birth control
"I had my Nexplanon device inserted about eleven months ago.  The only side effect I think I've experienced is spot bleeding.  For a while it wasn't so bad- I wouldn't have my period for a very long time (like two months) then I would have it for longer than I used to with a different consistency (over a week).  Now, I pretty much bleed randomly all the time. It makes my sexual life difficult.  I will probably get it taken out at my next gynecological exam."
