Late period but negative test??

Chelsea • Married 7 years 1 wonderful daughter & due w/ baby #2 June 2019

Had my nexplanon removed right after af was over and now I’m due for af and I’m late but pregnancy test was negative the AM? I’m confused😐😬hell? I wanna know what’s going on!!

Fyi: I had normal periods before having nexplanon removed that’s why they removed it..
