"i got nexplanon inserted about 8 weeks after birth, the end of april. i&#039;m breastfeeding, so i had no period within those 8 weeks. the first week of insertion, i had no bleeding whatsoever. had a minor headache shortly after insertion and had an ugly bruise for a while, but as far as side effects, that was it. the second week on it i started my period. i bled for about 7 days. after that, i was spotting lightly on and off for another week. since then i have not had any bleeding. i was nervous about getting the implant based on bad reviews, but i&#039;m glad i did. love it!"
