Baby or no baby

Tess
I have had so many time where I have thought I was pregnant and then take the test and there all negative. But these last few days I have been very tired I have slept from 9-12pm the next day and I still could sleep some more when I wake up and I have been really sick to my stomach yesterday and today. I took a test yesterday but the screen of it was really weird kinda seemed like something has messed up but I could tell it was negative. I am 7 days away from my period so I'm not gonna test again until I miss my period. I'm just stressing out bc I want to know if I am or not.. Any advice??
