So I used the restroom and then went to sit back in class and about 10 min later had a gush of fluid that soaked my panties and went a bit through my pants. It was clear and thin. I have not leaked more but just feel wet down there. I used the ph test strips for an aquarium and the wet underwear turned alkaline (8+ ph) but the opening of my vagina was acidic. Any idea what is going on?!?

I know urine and vaginal secretions are usually pretty acidic
