Nexplanon prevents pregnancy by continually releasing a low dose of progestin over a three-year period. The amount of progestin released slowly decreases over time.

Following your period, brown discharge is in most cases simply blood that has taken a little longer to be expelled.

Why is my pregnancy test line so faint?
