Already dilated!

ch

So I had some pressure and pain down low and in my back all night and this morning. So was told to go to L&D. Come to find out I'm already 1 in a half cm dilated and 80% affaced at 32 weeks and 4 days. They gave me medication to calm my cervix and hoping that helps. Hoping they dnt put me on bedrest the rest of my pregnancy. Anyone have this happen and be put on bedrest??
