"my experience with nexplanon hasn&#039;t been the greatest. i got it inserted in august 2014 and had my normal period at the end of that month. it lasted about 10 days and then stopped. i then started back again 3 days later and it lasted a further 3 days. i then didn&#039;t start back until the 27th of september 2014 and have had constant bleeding since. i decided to go to the doctors on jan 6th 2015 because the bleeding was becoming a hassle. she prescribed me loestrin 20 pills to take to stop the bleeding. i started taking them that day and my period stopped within a week...for one day! my period started back the very next day(15th jan) and is getting heavier rather than lighter 2 days in (17th jan). prolonged bleeding is the only side effect i had."
