3rd trimester exhaustion

Did anyone or has anyone felt extremely fatigued their last month of pregnancy? I feel like a walking zombie. All I want to do is fall asleep any time of day. My energy level is at a 0 and to top it off I have a toddler to chase around all day. I don't remember feeling this awful with my first, but then again I was able to sleep whenever I wanted to. My s.o works everyday so I can't ask him to take over so I can sleep. Baby isn't even here yet and I'm sleep deprived. 😖😢
