Confused???

I’m 6 days late and I took a test the first day of my missed period and it was negative. I’m hungry, all the time. Today I had a big lunch and then got home and had a snack. Not even 2 hours later I ate a cheeseburger 2 bratwursts and chips. I usually get full after a big lunch and that’s it for the day and maybe a snack later but today I feel like a bottomless pit. IM STILL HUNGRY. My acne is acting up like it does when i’m on my period but I still don’t have one. Do I test again?? Im starting to think the first one wasn’t accurate... I took it at night and on the first day of my pissed period. So should I just test again?
