please please help me I'm so scared to deliver!

I am 16 if some of you don't know. And I weigh 117 pounds and I'm only 5,3. My hips aren't wide at all. I feel like I won't be able to have my baby naturally because of my size.. If any of you are as small as me and gave birth naturally please let me know cause I am so scared. 😩😖 I can't sleep thinking about it.
