.5cm dilated 80% thinned?!

A

Just got back from L&D because of contractions and they said my contractions are around 2/3mins apart. She checked twice and no dilation improvement at .5cm (a finger tip), cervix super high up and 80% thinned.

Anyone have similar experiences? Or have any advice on how to jumpstart this? I was going to get a membrane sweep Friday but I’m not dilated enough yet..
