31 weeks as a CNA

Does anyone have any tips/advice for someone in their 3rd trimester and working as a full time CNA? It’s starting to hurt, especially if we are short handed. I have more Braxton Hicks when I’m at work than when I’m not, and even though my dr said I’m fine with lifting I’m still scared as I have an anterior placenta. Any tips on how to manage the pain? I have a belly band already, but my sciatica is still hurting. How do i survive the last 2 months??
