Developing lactose intolerance during pregnancy

Is it possible to develop a lactose intolerance during pregnancy & only have it while pregnant? I’m a FTM & ever since getting pregnant consuming diary products has been hell for me. If I have a glass of milk not even 20 minutes later I get terrible abdominal cramping, (TMI!) a bad case of diarrhea & nausea. Before getting pregnant though I could drink all the milk & eat all the cheese I wanted to & be fine. So is it possible to develop a lactose intolerance while pregnant?
