Period or pregnancy symptom

I have some discharge it’s white and kind of creamy not stretchy at all there’s no odor to it and it’s only on my underwear never when I wipe.I do not have any type of infection I feel totally fine,Just unsure of what this might be AF due in 4 days but having a lot of pregnancy symptoms who can tell the difference anymore 🤦🏻‍♀️ period or pregnancy ???
