Switching jobs?


Anyone every changed jobs during pregnancy? I'm 20w today and am so exhausted. I'm to the point where I'm so tired I cant keep up at work any more. I'm a manager and we are implementing a new program and that is also getting me behind in my work. My employees take advantage of me and try to make me work like 45 hours a week. I have told them both I'm tired and can't do it but they don't care. I don't know what to do but I know I can't keep doing this. Thanks
