Period is late!!

Sabrina

My period is late by 2 days according to the app which I usually start 1-2 before the app says I’m going to anyways. I have taken 3 home pregnancy test and and 2 was negative and one had a white line immediately show up! I have been nauseous for about two week and I am constantly exhausted!! I have a appointment with my obgyn in 2 weeks (they have nothing sooner) I’m just very impatient I want to know!! Can anybody give me any tips on what to do or try?
