100 effaced 1 cm.

So yesterday I was having bad contractions close together! I get to the hospital that I'm supposed to deliver at & they check me give me IV's etc. I learn that I'm 100% effaced and 1cm dilated. I am 32w4d pregnant with twin boys. I had to be transferred to a hospital with a NICU of course. I got here they checked me again & gave me medication to stop my delivery. I'm just wondering if anybody else had something like this happen to them? And when did you end up delivering cause as of now I can feel small cramps approaching again.
