2cm but no pain

HI guys,just wanna ask kung ano pwedeng gawin to make my cervix thinner. 2cm nadaw ako sabi ng rm ko pero no pain parin, nadilate na nila ako knina,makapal daw ang cervix ko sa labas, sa loob daw bumubuka na. What should I do po? Im 38weeks and 6 days based on lmp,but 37 and 4 days based on ultrasound. Can u give me any tips to make my cervix thinner? Thanks
