Cervix not dilating

Hi mummies, I’m in week 38 going 39 and having very constant contractions, 5,1,1.. went to hospital and my Gynae say I’m actually already in active labor however my cervix is just not dilating, still 0 since week 37 contractions.. any idea what to do/ eat to get the cervix to thin out and dilate? Anyone experienced the same thing before? I’m a first time mom.. thanks
