What exactly is nexplanon used for?

Birth control: It is subq implantable, i personally do not like it , works for birth control but often causes a lot of break thru bleeding and sometimes can be hard to get out, i like low dose pills better like loloestrin, if u do not want any more kids, I do if office trans cervical tubals, easy takes 5 minutes, if u change you mind it can't be reversed, but u could do in vitro fert.

Contraception: Nexplanon is an implantable contraceptive; for prevention of pregnancy.
