"i got my nexplanon inserted sept. 16th, 3 days after having my son. i&#039;m not sure if these bad side effects i&#039;m having are from the implant or postpartum stuff still. no bleeding anymore, but having a horrible foul discharge daily along with irritation and dryness. i thought it could still be post partum lochia , but now i&#039;m not sure reading that a side effect from nexplanon could be vaginitis. also am noticing headaches and breakouts more than usual. if this continues, i will not continue this method. so far not so good."
