how did you know?

Marie

for all the women who have gone through childbirth, how did you know when it was time to go to the hospital? i already had one false alarm, I was having regular painful contractions 5 minutes apart for over an hour, accompanied by back pain, but got sent home because I was only dilated to 2cm and didn't progress. I'm really worried that I won't be able to tell what's real labor and what's not... advice please!!
