Stopping work before baby?

Jenna • Wifey💍Mom of 2💕

I want to make my Last day of work next Friday (I’ll be just about 37 weeks). I’m just tired and want sometime before the baby comes and my job is somewhat physically demanding and becoming too much. Would my doctor give me a doctors note to say I can stop working without a problem? I’m not getting paid maternity leave at all so that’s not an issue.
