birth control
"I got the Nexplanon insterted on Jan, 22, 2015. (Fast, painless, bruise smaller than a dime). Around February 15, I had my normal, 4 day period but experienced extremely light spotting on and off for the next 4-5 weeks . (It was so light I didnt need a panty liner and an Ibuprofen would stop it temporarily for intimacy). It is now late April (same year, 2015)  and it seems as though my body is back to how it was pre-insertion. Other than the initial spotting, I have not experienced any other side effects."
