"i got implanon inserted august 2014 right after my first period after having my baby. the first few months i had no period. then i started having light periods that lasted about a week compared to 3-4 days before getting pregnant. i&#039;ve also gained about 20 lbs since insertion. it helps a lot with my pms, and i often forget it&#039;s there. overall i love it and plan to have it reinserted when my 3 years are up."
