Anyone facing the same issue as me

I am currently pregnant at 30 weeks. All housework I still have to do. My husband is busy working and he always have night meeting till very late and have to help me. My husband brother not working always don't help cleaning up after eating or just leave it on the table and waiting for me to help him to wash and throw all the stuff. I am very tired of it already. This is not the first time already. MIL also doing the same things helping his sons to talk say his son is very busy always and rushing for his stuff. Make me do all the house stuff and carry heavy stuff sometimes and also help them to buy things.
