Need some insight please.

cd 38 when i wiped earlier. (pic in comments) I've been feeling terrible since sunday. took a test yesterday and it was negative. been feeling alright on soup and crackers felt better tuesday so i tried a sub for dinner and that was a mistake. stomach has been yucky ever since. want to try to eat soup but i seriously have no appetite whatsoever. looking at any food makes me sick let alone have wet soupy noodles in my mouth lol
