When is it that they admit you to the hospital. I've heard you must be 4cm then they admit you. But does that still apply if you're not having regular contractions? Or will they induce you? I'll be 38wks Saturday & I go to the dr Friday morning. I was 3cm dilated last Thursday & I definitely think I've dilated some more since then, I've been having lots of menstrual like cramps & some lower back pain & some traces of mucus in my urine. And I'm just wondering if I am 4 or more cm dilated what they'll do?
