Help!

Okay so my scheduled csection was set for Friday June 2nd. Due to high blood pressure today it was moved to Tuesday morning the 30th. My dr told me to be on strict bed rest until then but if something's wrong go to labor & delivery. Me being stupid didn't ask what he meant by that. 
So besides my water breaking/contractions, what did he mean? 
Like if what happens should I go into L&D?
