Pregnant or?

Jade • Expecting my first 12/24/19❤️

My period is now 15 days late.. I tested 2 days ago and it was negative. How likely is it that the test just isn’t picking it up? I’m so nauseous, tired, & sensitive to smells. I’m calling the doctor in the morning to try & get a blood test but I just was curious how likely it is that I’m pregnant.

Anything helps
