Woke up sore all over

Christina • 22yo. Ftm. Happily married. Due on January 8th with a baby girl 💜👶🏼
I'm 37+3 days pregnant today, been waking up all night feeling sore. Now up hours before I should be just feeling like I've been intensely cleaning and scrubbing all night. I felt fine before bed which is why this is so strange. Any ideas or similar feelings?
