"i got nexplanon about 3 months ago. my doctor had so much hope in it. i&#039;ve always had irregular periods and that&#039;s why she thought it would work so well. when i got it implanted i was on my period, then it stopped for about a week or so. the next week i&#039;m spotting and before you know it i&#039;m bleeding, spotting, bleeding, spotting. i haven&#039;t had a day go by where i&#039;m not using tampons or pads. i did notice major hair loss and i&#039;ve gained 7 lbs already. i also got a concussion a month ago and i think the nexplanon has made some of the symptoms much worse such as headaches, sleep, mood, and energy level. i&#039;ve been trying to wait it out, but i&#039;m going to call my doctor soon."
