When did you ladies go to the hospital or birth center once contractions started? Did you stay at home until contractions were a certain time apart? Did your doctor tell you to stay home until a certain point? I'm just curious, this is my first baby and I'm only 27 weeks so my doctor hasn't said anything yet.  I've been reading about all things baby/pregnancy since before I was pregnant and I see stuff where people say they were in labor for 20 hours, are they in the hospital in labor for 20 hours?
