When to expect labor?

So I’m 38 weeks, and yesterday I got checked and I’m only 1cm but she said that I’m SUPER soft and about 75% effaced. She also said she can already feel his head, and that my cervix is in position for birth. I go back in a week but she said “if I’m still pregnant” and that he can come any day. That’s giving me so much anxiety and I just want to know like my chances of him holding off vs coming early.
