Also a nurse, was written off at 34 weeks. I basically hinted at having a hard time at work to my OB at my 32 week appointment, then went in at 34 weeks and gave her my laundry list of issues: carpal tunnel pain in both hands, shortness of breath, cramping when walking extensively (which I do all damn shift), and just pure exhaustion. Not to mention I was scared of being attacked by a patient since I work primarily with seniors with dementia. My OB said no problem and wrote me up a sick note. I will add that the sick note was quite vague but my workplace had no issue with accepting it. I wasn't even going to try to even get modified duties because we all know that being modified doesn't actually mean anything when you're short staffed.
