If you are 36 weeks pregnant I really suggest that you make them do bi-daily obs on you, as you are getting close to your due date and this is where pre-ecpampsia (sp?) can kick in. I think you shodl go back and tell them again abtou the blurred vision and headaches... Ham it up a little, make I out a little worse than it is to get their attention.
This is not somethign you want to risk hun.
