Im doing the implant as well.
Simple it goes in your arm n stays for up to 4 years.
J would do depo but got this baby on it.
Im gettin the mirana (if thats the proper spelling)
I had Implanon! (I think it is now called Nexaplon) & it worked awesome for me! I got it taken out the 28th of march. & found out I was pregnant the 24th of april! So my fertility returned quick if you change your mind! ;)
Im using depo provera i loved it and had no side effects except my period being irregular the first 3 months
