"i got my nexplanon inserted on 04/12/2012 which was day 3 of my cycle, bleeding stopped 2 hours after insertion. i have had some unpredictable bleeding, mostly waking up bleeding and then by the end of the day there would be nothing. i have had no other side effects and since hitting the three month mark i haven&#039;t had any bleeding. i&#039;m very happy with it. i was worried about my weight being an issue, as i am very overweight but my ob assured me it would not be a problem."
