Possible labor signs?

I'm 33wks2days, but have been noticing some weird things my bodies been doing. I've definitely been nesting this whole week out of no where. Also last night I could not fall asleep for hours because of urinating like 3 or 4 times. Also my legs were restless, and I felt extremely nauseated. I felt a lot of pressure in my lower stomach. Almost as if the baby was gonna fall out. I've had three bowel movements in the last day, and I'm usually constipated. Any help?!? I have an appointment Monday so I don't really want to ha e to go to the hospital.
