Ok I went to my doctor appointment yesterday and they said I was 5 cm dilated I'm only 33 weeks they have been giving me pills to kinda slow down contractions on Christmas I was having uncomfortable contractions but they passed then yesterday when I got into labor in delivery I was having them kinda bad until the pills now this morning more of my mucus plug feel out so does this mean labor is progressing?
