My Todlder is so tough right now help!

Hello everyone, I have a 2.5 year old and omg I think it’s the worst age, plus I’m 36 weeks pregnant. He screams, yells, throws toys , hitting kicking, and says no all the time. My husband and have tried to provide activities, choices, understanding and being there for him when he has big feeling, but he just seems like an evil child. Bed time is ugly in our house hold, he just won’t listen, if anyone is going through the same situation please help with some tips. I’m going insane. When does this stage pass? I miss him being just a little human.
