How hard does it get after week 20?

I am thinking of changing jobs/teams. My benefits remain the same, but i am worried about stress and anxiety that might affect baby and pregnancy..

I am currently very unhappy with ky current job situation and know that it is going to get much bad in coming months.

But if i need to switch, i want to do it before the baby comes. I am 20 weeks, and have 3-4 months before i start my leave.

Anyone’s experience or opinions greatly appreciated.
