Depends: If you have no maternal or fetal complications, it is not unreasonable to work as long as you physically feel able to do so. However, if you have signs or symptoms of ptl, hypertension, fetal growth or amniotic fluid issues etc., you need to discuss with your doctor.

Luisten to your doc.: If you tell a patient to not eat on one side for awhile, or to not rinse for a few days, you have a reason. Your doc must have a reason for his instructions. Listen to him or her.
