TMI!! Lactose intolerance while pregnant

This story is a little tmi, but I think I may have recently developed lactose intolerance. I'm almost 9 weeks along. Prior to the pregnancy I rarely ever experienced discomfort after consuming milk products. About 2 days ago I had a bowl of cereal and drank the milk out of the bowl, shortly after I had to go to the bathroom and my stool was normal, but 10 minutes after that I had to go again and it was kind of loose, but I didn't think anything of it. Today I had maybe half a glass of milk and right after I drank some of it I had to run to the bathroom with diarrhea. I had to go about 4 more times after that. The stomach cramps while using the bathroom were awful! I thought about going to the hospital to make sure baby is ok, but I haven't had any bleeding so I stayed home. Has anyone else developed lactose intolerance during pregnancy? And for those who have it, do those symptoms sound like it?
