Fatigue in day but waking in night a lot!!...

Anna • First time mummy to be

I get bad fatigue in the afternoon so come bedtime I’m exhausted. I fall asleep then wake in night..like 2/3 a.m. I go to the toilet then can’t get back to sleep! If I do it’s lots of weird dreams and waking in between them! Is it hormones or my subconscious processing everything. I’m 😴 tired. Anyone the same?
