lactose intolerant because of pregnancy?

This is my 2nd pregnancy & it's taking a toll on me. Everything I didn't have with my first, I have now. But I feel that since I got pregnancy, I can't eat or drink dairy products. I was eating cereal for the first time in a while (My first won't eat if I don't eat along with) & I started getting nauseous & gassy, my stomach started hurting as well. I always used to drink warm milk before bed and now I can't even do that without feeling nauseous or uncomfortable. Can pregnancy make someone lactose intolerant? I never was but seem to be now. 😞
