Having trouble sleeping... Any ideas?

Katie • 29 years old
I have been having trouble sleeping the past few nights. It takes me about in hour to fall asleep now, even when I'm tired. I will wake up at 3 or 4AM and it will either take an hour to fall back asleep or I won't fall asleep again at all. I just can't get comfortable. I'm sleeping on my side, which is normal but since I've found out I'm pregnant I've found it more comfortable to sleep on my stomach (which I have been trying not to do). I'm either super hot or super cold at night too. I am only 5 weeks pregnant.
