Lactose Intolerant when pregnant?

Haydee
Hi all,
So this is my first pregnancy. I am 11 weeks and since the very beginning I have not been able to tolerate any dairy. I can't eat ice cream, I can't drink milk (not even soy milk - I know, it's technically not dairy), yogurt... Nothing. 
The only thing I can eat without a problem is cheese. 
I literally get the worst tummy aches, and veery nauseous. 
Also, I have always been obsessed with chocolate and I can't even handle a Hershey's kiss. What is going on!? 😩
Does anyone else have this problem?
