Milk with cereal

Idk why but everytime I eat cereal the milk always taste really disgusting to me like I’m allergic to it or something but I’m not having a allergic reaction 😩 and then I get super nauseous after having it, it really sucks because I’m pregnant and I be wanting cereal but I guess my body just doesn’t go well with milk. Ik it isn’t because I’m pregnant bc there is a difference like it wouldn’t leave a nasty taste in my mouth and I would automatically throw it up if it was bc I’m prego . Just curious if anyone knows why milk does this to me ?? If I was lactose intolerant wouldn’t it act the same way towards food with milk ??
