Lower side of normal AFI ? HELP

Hi glow mammas.Iam 16 weeks today and have got vaginal discharge since the beginning but yesterday it came like a gush of fluid just running down my vag and i was shit scared. Went to the doctors and she did an US and told me my amniotic fluid is on the lower side of normal (8cm) baby was good , movement was good but ive been first of given antibiotics just in case there is a leak and she diagnosed vaginal yeast infection so gave me meds for that too. I have to go again next monday for another US to see how my levels look. Im worried. What should i do ? What can i do ? Please respond 😭😥
