This may be the first week you feel your clothes start to tighten as your breasts and belly expand. You won't be visibly pregnant, but even if you're partial to form-fitting attire, those relaxed fits might find their way to the front of the closet.
You can sort out all that stuff with the wardrobe, of course, if you can stay awake long enough.
At this point, you're probably tired. Really tired. The baby-making hormones are pulling a number on you. And, of course, all that puking and peeing can take quite a toll.
