6 days!!! I was so frustrated because I thought for sure labor would start soon. It didn't. This was a second pregnancy and I had 3 weeks of false labor (not solid 3 weeks, but on again/off again...just enough so I couldn't sleep well).
When I finally went into labor, I didn't believe it and kept working. I was taking care of a labor patient on my OB floor when I finally realized it was real labor and had to excuse myself, first for a "break" while I went to triage, and second, for good for a leave of absence
I did find someone to replace me as a nurse first
