35 weeks

I will be 36 weeks on Wednesday. I've been having contracting on and off for the last couple weeks. Since last night theve worsened a lot more. And I've been having them all day today. Last week I was 1cm dilated, and they said no need to go into l&d till my water break or I'm bleeding. With my other two my water didn't break till I was in the hospital and they don't know when it broke. How much longer do I have to go???, since I've been contracting all high and all day today?
