No appetite food taste gross

So im 8 weeks today. Ive hardly been eating much for at least the past week almost two. I havent been vomiting until today but i do get nausea alot. Nothing specific has made me feel like not eating i just have no appetite at all. Today my husband brought home pizza for all of us (we have 3 boys). Normal regular pepperoni pizza. Same place he gets it when hes in the mood for pizza. I swear i took two bites and busted out in tears. I dont even know why i was crying. It tasted like somebody dumped a whole bottle of hot sauce on my food! I ran in the bathroom crying then started vomiting my guts out which mostly consisted of liquids. He tried to give me his but it tasted the same. It burned my lips my tongue my whole mouth was on fire. This is my fifth pregnancy. Ive never experienced anything like this before. Anybody have any ideas? Mind yOu there was nothing wrong with the pizza it was just me
