Cervix unreachable

Hi everyone. Last week I was 38 weeks and 4 days and was 1cm dilated, earlier I visited my OB (39 weeks and 4 days today) but upon IE she can't reach my cervix, so I dont know if I dilated more than 1cm. I do prenatal yoga, walking, sitting on a gym ball, but I don't know. Now I am worried and stress out. I really wanna cry. Does any of you experiencing the same? By the way this is my second baby, my eldest is 4 years old. #advicepls
