Sudden Weight Loss Concerns (also on May 2012)

so since about 17 weeks I have been gaining weight pretty steadily. Up until last week I had gained about 8 pounds total. However, these past three days I have been losing weight really quickly (a pound a day). I'm kind of starting to get worried. I have changed my diet. I still eat about the same amount, but I have been making healthier choices. I also have started drinking a lot more water and I am back to a regular exercise routine which I had neglected over the holidays. I have an OB appointment Next Tuesday. Should I wait until then to consult my OB or call the office sooner?
