TMI but help would be appreciated 🤷🏻‍♀️

So before pregnancy I was hooked on chocolate milk, I’d drink 2L every day-two days but one day it just started that anytime I drink any kind of milk my stomach rumbles for the next day and the gas I pass which is a lot when I drink milk, smells absolutely rotten like it does not smell normal for me at all or even from the start of this pregnancy. It’s disgusting and I always get loose stools after drinking milk or chocolate milk like an hour or two later. Is it possible for this pregnancy to have turned me lactose intolerant?
