Decreased work hours until maternity leave

Im 30 weeks pregnant and a first time mom.

Has anyone else felt the need, or has had to, decrease their work hours? I plan on starting a 12 week maternity leave right as baby boy arrives, but until then I've decreased my work hours from a 40 hour work week to a max of 30 hours a week. I've felt more tired, stressed and very uncomfortable lately. I know there's still 2 more months of this, but I can't handle as much of the work and home chores like I want to. Prenatal diabetes has kicked in too with me during the start of the third trimester.. and that's been hard on me too.
