Sudden sensitivity to food?

Leah

Hi! I’m 12 days DPO and for the past week I’ve noticed a sudden sensitivity to food I never had. I love spicy and all of a sudden I couldn’t eat sriracha (which I normally use tons of). It was too spicy and burned my tongue. Olives also tasted funny as did my favorite cheese. My husband told me they all taste normal. Never been pregnant in the beginning of TTC. Thoughts?
