Nexplanon

Gabby • Engaged to the love of my life, and mommy to Elias Joseph 9.2.16💙

So I haven’t had a period since before i had my now 12 month old. So that was back in November 2015. Had my son September 2016, Nexplanon inserted in October 2016.... i just went to the bathroom and when I wiped there was light pink blood??? I mean, it was after I had sex but sex is a 3 time a week thing for us so I’m assuming that, that’s not a factor? Has anyone else been on nexplanon and get a period a year later after not having one at all????
