So.. can’t determine what this is 37+6

Yesterday I posted a photo of liquid that came out when I sat on the couch. Well it never did it again after doing the panty test and such so I figured it was discharge.

Now today, twice, this has came out. There’s no odor/itch, and I could see it with a mirror before it came out. It looked white/milky. Then when I wiped, this is what it looked like... is this an infection? Discharge? Fluid?

I can feel like fluid or something is gonna fall out of my vagina but sometimes nothing is there. 😩😩
