Anyone wake up in the middle of the night for no reason and have an extremely difficult time going back to sleep? I'm 4 weeks 5days.

I wake up around 4:30am or 4:50am every morning. This has lasted about 6 days now. I have been exhausted every day it happens. I'm trying to avoid caffeine, so this is making coffee even more tempting. Anyone else do this? Does it eventually stop?
