spotting after a 12 day missed period?

I'm so confused. I was 99 positive I was pregnant. I don't know what's going on?

    Sometimes pregnant women will spot too, call your doctor when you can. If it were me and it gets any worse I would go to see a doc right way. But that's just me. Because I've been trying so hard, I would get too nervous to wait.

      My aunt bleed extremely heavy and had a healthy baby. It was very weird. But I've never been late and had a period

        You can still spot if you're pregnant. Have you tested? I'd check with an OBGYN just to make sure either way, and if you are, make sure everything is good.
