OOo, are you feeling ok? No nausea, dizziness, pains?
My mother tripped and fell all the way down a flight of stairs when she was also 35 weeks pregnant. Everything was fine. She went to see her doctor and he told her to rest and be more careful.
Call the doctor and let them know what happened, just so they can have a record of it. If you are home alone, call someone and ask them to come over if you start feeling really tired.
