change in discharge color

bee

i have a concern that has recently came about in like a span of 2 days. my discharge has always been clear but now it’s like this yellowish color which is strange. when I wipe, it’s clear but now I can definitely see it.

I have also been experiencing lower abdominal pain on my left side, but it hadn’t been enough to affect my day to day life. it made me think I was getting my period yesterday, and I was also moist but it was just discharge. i don’t get my period for 6 more days.

i also noticed sometimes it will leave this white stain in my underwear that discharge normally doesn’t leave. just a fyi, i am a virgin and having an std is not in the options.

what do you guys think it is?
