AF in 1 day

AF is due in 1 day according to glow and I have been having food aversions to the point I’ll eat maybe 1 or 2 things, craving curry like mad, having sharpish pains in my side, drank a summer fruits squash and about 20 minutes later it almost came up(I couldn’t drink this squash in my first pregnancy as it would give me heartburn and make my morning sickness worse) and then this morning I was lying in bed and almost threw up (I didn’t but almost) I have also been tired.

Normally when aunt flow is due I eat everything in the house, I get bloated, and poo a lot. I do get tired aswell.

Could this be a sign of pregnancy? I have done a test yesterday with afternoon urine and it was negative.
