how long did you ladies work during you're pregnancy?i worked until I went into labor with my first, I'm 27 weeks now but man oh man I'm just getting so tired and drained with these 9 hour shifts.. and if I ask for less hours or days I'll go back to part time. I don't wanna stop working just yet but I'm so drained
