Pregnant or not?

Had unprotected sex last month, realized that I was doing it during my ovulation window, not the actual day, so quickly stopped doing it. Got my period like normal, now I’m very irritable and just feel really hormonal. Certain foods make me gag. I’m super horny but I’m too lazy to do it. Not sure if I’m pregnant or not. I’m leaning towards not. Anyone had something similar happen and end up pregnant?

Maybe I’m hormonal bc I’ve gained weight, have recently moved homes, am under stress, and am out of my routine.
