cold foods and feeling defeated! TWW

I'm only 3/4 dpo but I already counted myself out this month because I don't "feel any different" and I keep telling myself I ruined it because I've been eating cold foods and had ice cream. Am i being too hard on myself? I know that 99% of people don't have symptoms this early anyway because there hasn't been implantation yet. This tww is driving me nuts! Does cold food really ruin it?
