Dear...amniotic fluid can't be increased like that. A normal index being 8-10, AFI <6 is oligohydramnia. Normal delivery also depends on the position of baby inside , if you get labor pains they will surely try for normal first.
Next Steps
your wt. , baby wt. , baby comfort , baby position, many things has to be seen for attaining normal delivery.
Health Tips
don't panic, normal delivery is possible but only if the baby is comfortable , if baby is feeling suffocated due to low amniotic fluid index , am sure you will not opt to wait and put him in danger.
