Has anyone else noticed a change in their sleep pattern during the 2ww? This is my first time noticing it. I slept fine before this 2ww. I have been waking up at the same exact time, 4:30AM during the last week and have a hard time going back to sleep. Does anyone elseโ€™s sleep get disturbed by hormone fluctuations? I read that could be a reason. Stress could be the cause too. Iโ€™m so tired this morning.
