So I got my nexplanon January 23rd 2017 (2nd time getting it)

I haven't starter my period for 2 months Now my last period was January 9th-28th

Had my daughter November 15th, 2016.

The very first time I got my nexplanon in like 2014 I got my period every month normal and everything and Now I haven't gotten it in 2 months!!!

Like I feel pregnant, morning sickness, nauseous head aches .... Has anyone gotten pregnant while on nexplanon???
