You could be in labor for a looooong time before you reach the 511 rule, so no, 2 hours doesn't seem like a long time. Did she say contractions 5 mins apart, lasting 1 minute, for 2 hours?
I don't recall him saying anything about how long or far apart they are.
He just said how will you be able to tell false labor from real labor? drink water...[something like this. I have to ask at my next appointment bc i forget! :(] I guess if its false labor, it will stop. and if it's real labor it wont.
He just said I want to hear from you if your water breaks or you're having contractions for more then two hours.
