Husband doesn’t understand-rant

I’m 36+4 with a almost 2 year old wild child and my husband just doesn’t understand why I’m exhausted and asking him for a bit more help with her. It’s so frustrating! We both work full time and I am going to work until I have this baby and just need some extra help at the house and with our daughter but he seems to think I’m using pregnancy as an “excuse”. Anything I can say without starting an argument (don’t have the patience or energy to argue right now).
