8dpo symptoms

What symptoms should I have if I'm pregant? What should my cm look like? I been feeling werid emotional and hungry and pooping alot as well but its hard to tell cuz I have all these before af which is due in 5 days but I was told cm is a good indicator idk cuz I never tracked any of this when I had my first two and I know every women is different but can someone explain what I need to look for besides a missed af
