So I’m a bit confused

I’ve taken pregnancy tests and only ones that forsure come back positive are the equate Brands which I know suck.

Today is the day of my expected period so I took a dollar tree test and looked negative.

As I was finishing up peeing I wipe and see clear discharge mixed with light pink blood.

What could this mean?

Could it mean my periods coming ?

Should I test again in a few days?

I have had period / pregnancy symptoms so I’m a bit confused.

Appreciate any insight!!!
