Light faint yellow clear string discharge

Hi was wondering did anyone have this at 10dpo

Sorry about tmi

I was peeing then when I wiped on the tissue had this long string clear/ faint yellow discharge which resembled as snot.

I was wondering if anyone previously had this? Menstrual is due in two days but no sore breasts or anything that I usually get before menstrual.

I tried a pregnancy test but it was negative yesterday.

I don’t know what’s going on did anyone get a positive test after they had this discharge?
