PLEASE READ!! I have questions..

MamaBear
I'm a FTM at 37+2, I was checked at the doc yesterday and my cervix is VERY soft, I was dilated 1cm, and doc could feel baby's head. This afternoon I lost my mucus plug. Now I'm having period like cramps and I can feel baby's head putting more pressure down there. How soon do you think I'll go into labor?? What about you? How soon after one or more of these signs did you go into labor? I'm really nervous/scared/excited.
