Thank You! I Drank Moldy Water Accidentally. I Use A

Thank you! I drank moldy water accidentally. I use a Brita water pitcher in my refrigerator and did not notice the floating black and gray specks in my glass of water until I drank about two large sips. About two weeks ago I had changed the filter. This is a rather new pitcher so I was very surprised to see black mold on the filter and covering the bottom of the pitcher tonight. What should I do? What should I expect?
