Lactose intolerant during pregnancy?

Carina • Due April 2015 with my first child.
I am 9 weeks pregnant today. In the past few days I been getting the worst gas pains I have ever experience. I have Never had a problem with milk in fact I drink milk twice a day since I was little. But I think now that I'm pregnant is giving me problems. Does anyone else have a similar experience? You is possible for me to become lactose intolerant after pregnancy? Thanks!
