I have my first ultrasound at 2:20pm this after noon. I went to sleep at 8:45pm last night or so and I woke up at 12am and have not been able to sleep at all :( I wish I could but for some reason my body won't. I hope your ultrasound goes well. I'm currently 8w4or5d :)
Completely normal... I'm not able to sleep throughout the night anymore I normally take cat naps lol. Good luck on your ultrasound!
