Pregnant or no

Sunday I had super light pink spotting that I could only see when I wipe, it happened once and I thought it was my period starting which was really early bc glow says I should start Friday or Saturday . Yesterday after sex I wipe and saw the light pink again but it was gone after the wipe. Has anyone else had this happen? I would take a test but since I haven’t missed my actual period yet I’m waiting. Thoughts?
