Blood tinged EWCM during time for period?

One app says I was supposed to start 7/3, Glow says I’m supposed to start today, and another app says I’m supposed to start 7/7. I’ve been spotting since 7/3, but it’s not enough to even wear a panty liner. It barely shows on the toilet paper. Please excuse the photos, I made a makeshift tampon 🤣 anyone experience this? Is it an early sign of pregnancy?
