first time mom question

Ka

i’m 35+5 and i’ve been feeling my baby in my pelvic area since 35+1 and i had a appointment today i told my doctor and he checked me and he said i have not dilated yet but he for sure felt my babies head down there and i was right he is in my pelvic area... has anyone every heard that considering you’re not dilated? and how long after did you give birth...i want him to stay in as long as possible 😩
