"i got my first implanon (nexplanon) in september 2011. at first, i had irregular spotting, no cramps or mood swings. after a few months the spotting slowed to a halt.  i got the nexplanon replacement in 2014 and after a year, i have only had one spotting occurrence. this amazing! i am so unbelievably satisfied with this product that i cannot imagine the day i try to get pregnant and have to go without it."
