height and pregnancy

im not pregnant, im 17 and do not want a baby yet but i have a couple of questions for when i do become pregnant:
1. being just under 5ft am i going to have any complications?
2. does being just under 5ft and having a short pelvis mean i would need a cesarean?and are their ways i can avoid a cesarean ?
3. will having a small torso mean i would show sooner?
4. since i have a small torso and legs am i going to be able to carry a baby to full term
