The implant (Nexplanon) is a small, flexible plastic rod about the size of a matchstick, which a nurse or doctor inserts into your arm. It releases progestin and progesterone hormones into your body that prevent pregnancy for up to 3-5 years.

Sometimes the hormones released by the implant change your period. How it changes is different for each person, but some have reported that after 3-6 months, bleeding becomes more regular and is usually lighter with less cramping. After one year, some people do not have any bleeding at all.
