"i had nexplanon put in last friday, six weeks post partum. i had not gotten my first period before insertion and still have not gotten it. i haven&#039;t had any bleeding or spotting. i&#039;m actually not having any issues at all with the nexplanon other than the ugly bruising at the injection site. i have read reports or headaches and depression but i haven&#039;t had that either.. no weight gain either, i&#039;ve actually lost 2 lbs since i&#039;ve been on it. hopefully none of this will change."
