Short answer: Yes
Long medical answer: "The cervix is long, thick, and filled with the mucous plug. By the 36th week, the vagina and urethra are elongated and all the tissues in the perineal region are enlarged, so the swollen perineum projects beyond the pelvic outlet in the last weeks of pregnancy, and is readily expandable during labor."
