From "What to Expect When You're Expecting"
Your baby is just over 2 inches long now and weighs about a third of an ounce. His/her body is straightening out and the torso is lengthening. Hair follicles are forming, and fingernail and toenail beds are beginning to develop (nails will actually start to grow within the next few weeks). Those nails are forming on individual fingers and toes, having separated recently from the webbed hands and feet of just a few weeks ago. And though you can't tell baby's gender by looking yet, ovaries are developing if it's a girl. What you would be able to see, if your womb had a view, is that your fetus has distinct human characteristics by now, with hands and feet in front of the body, ears nearly in their final shape (if not final location), open nasal passages on the tip of the nose, a tongue and palate in the mouth, and visible nipples.

This is going to sound funny, but I was reading in "The Pregnancy Book" and there's a section on things to expect this month. One of them is "vivid dreams". The book says since your hormones are still going crazy at night, pregnancy dreams tend to be more intense than pre-pregnancy dreams. It says that they will seem more real and more exaggerated. This is so funny to me because it's been happening! A few nights back, I dreamed I was running, and when I woke up I felt like I had REALLY been running. I had to lay there for a minute and figure out what had just happened. But the best one was last night... I woke up after having a very real dream where I was eatting cupcakes at a party. I think I ate about five of them, and I can still picture the icing piled on them. When I woke up, it's like I could taste the sweetness in my mouth, and I felt like I had a tummy full of sweets. Crazy?!!!! Made me feel better that it happens to other pregnant people. :)
