So AF is 3 days away and i got some really light bleeding today, doesnt fill a pad or a tampon.

No cramps, no actual period symptoms.

Im just assuming its AF BUT when i changed my tampon a bit ago i had some white discharge on the tampon too. WHICH IVE NEVER EXPERIENCED IN MY LIFE. It was like gooey & almost clear but had like a white tinge to it if it made sense.

Any idea what it could be??
