For the ladies who have had Prodromal for weeks...

How long did you have it before you actually went to the hospital and was in real labor? Did you know when it was REALLY time? I've been doing it bad for 3 weeks now and I'm afraid I'll end up delivering at home because as bad as it is, it has not been go time for real. I'm so frustrated! I also don't want to have my husband having to YouTube how to deliver a baby at home! Help!
