Early maternity leave

Audreana
I work at Wal-Mart as a cashier and I am 36 weeks pregnant.. working for a couple hours gives me.so.much pain and the pelvic pressure is getting worse. I honestly am over working I just wanna relax n stay off my feet. I will Still walk n not be completely lazy but I have worked my whole pregnancy n I feel like I'm beyond ready for some time off... am I wrong for wanting to not work
