I'm not scared but I feel like shit

So I'm suppose to start my period tomorrow and I feel like shit first started with cramping and now I feel naseous. I ate Popeyes today and idk I felt completely disgusted by itand I fucking love popeyes. I don't believe it's food poisoning cause I had food poisoning on Christmas nothing like that and everyone else ate popeyes and they're good. Could I be pregnant? I didn't know when my ovulation days were on this app but I had sex on every single day i was ovulating. I took a pregnancy test like a week and a half ago and I have one test left. I'm kinda secretly freaking out but maybe I'm just nervous because I'm suppose to start my pd tomorrow and if I don't I might break down and have a panic attack. Some support ladies ?
