Implantation or period?

Sharlissa

I've been spotting on & off for like the past week. I've also had very faint cramping as well. I never spot enough to fill up a liner. I only am able to see it when I wipe myself. Af was due between 4-8th and still no sign of her. Has this happened to anyone & they turned out to be pregnant 🤰🏾🤔
