"i got the nexplanon implant immediately after giving birth to my son on november 18, 2015. it was quick and painless. i chose this form of bc because i know i wouldn&#039;t keep up with pills &amp; this just seemed like the easiest way to go. plus its good for 3 years. five months have passed since having my son &amp; i haven&#039;t had a single period. i do get very mild cramps and weird cravings around the time i usually get my period. no bleeding whatsoever. i have had some negative side effects with this birth control. mood swings, severe headaches, hair loss and acne."
