Is it possible to be less dilated than before?

At my last appointment 3 days ago, dr checked my cervix and I was 3 1/2 cm dilated 75% effaced. I lost my plug that night but then no more blood the next day. I have had no cramps and I actually feel a lot better than before. Having less pain, more energy, and not really getting any discharge like I was. I thought I would be in labor soon but now I think I still have another week or so. Is it possible for you to go back down in dialation? Or has my body just stalled?
