Weird symptom of pregnancy?

OK this is gonna b a funny question. I am 35 yrs old. Mother of 3 great girls. U'd think tht I would knw a thing or 2 about being pregnant...but each time was very different then the last 1. So, it still catches me off guard. But here is my ?.....I have NEVER in my life had a problem w/milk. But within the last 2 weeks I have become SEVERLY Lactose Intolerant (like 2 swigs outta the bottle makes me sick as hell). Vomiting from it and all. I talked to my mom about it...and she had the same thing when she was pregnant w/me. Im wondering if tht could mean I am prego? I am only a few days late w/my period. And I dont think about it till I am at least a week late.
