"i have had the nexplanon since dec. 27, 2016 

i got my first period at the end of january and it lasted about a month and a half. in march of 2017 i didn&#039;t bleed for close to three weeks and then started bleeding again march 28th and have been bleeding every since. i have gained about 13 lbs so far since getting the birth control. although for now the weight gain isn&#039;t a deal breaker for me but the bleeding is..  i am trying to be very patient to see how my body adjusts to the implant. it has been three months so far and i have my fingers crossed that my cycle will go away for awhile."
