BabyD: 5w1d is so early for an u/s. I would imagine the main purpose is for placement, to make sure the gestational sac is on the uterus (I.e., it's not an ectopic). We saw a heartbeat at 6w3d. It was a tiny flicker and the dr said the baby was the size of a grain of rice.
AFM, so fatigue hit me like a bus today! I've had to take 1-2 hour naps the past two days, but today, I was awake for only 4 hours and had to nap for 2 hours. It's a good thing I'm on vacation, but not sure what happens when I go back to work on Weds. I had to cancel sightseeing and hope to at least make it to the hotel pool today. Anyone else experience this?
