pregnant on the implant

TwurlyGurl
I'm on the implant( a year) , my periods are always on time and I'm not sure if you could get pregnant while on the implant. But I'm two weeks late ( which never happens)  and I'm experiencing some early pregnancy symptoms! Yikes! I'm not sure if it's the hormones getting jacked due to the implant or if I'm just freaking or I'm that 1% of getting pregnant on B.C! Has this happened to anyone? Has anyone experienced this? 
All help, advice and anything else appreciated 😀😚
