When are you done with work?

I'm 27 weeks today and am on my feet for work alllll day with no breaks at a café. I told my boss January 10th will be my last day and she asked me "why?" With a weird look... Uhm because I can't handle being on my feet for 8 hours a day anymore😩 and the customers there are starting to drive me crazy lol it's just a stressful job I don't need right now. I wish I could work / make money up to my due date in March but I just can't do it anymore. I'm taking my time to rest! When will you ladies be done with work?
