TRIGGER WARNING ⚠️ Period or early MC/chemical pregnancy?

Emily

My period was 3 days late, I had every symptom and SWORE I was pregnant. Also had a faint line on Friday that went away the next day. Had bleeding with this today… is this AF or am I experiencing an early MC or a chemical that failed to implant? I never clot during AF and looks like my previous losses. 😢 Pic of faint positive in comments. I just like to know what’s going on with my body for future TTC efforts.
