Sound like chemical?

Sunshine

At 10dpo I had IB... light pink spotting, it only lasted like 4 hours, but it was only present when I wiped.. on 12dpo, I got a faint positive. But this mornin when I woke up, I had slight... dull... abdominal cramping.. and I'm bleeding.. like bleeding bleeding. It's not much to full a pad, but it's definitely enough to fill a panty liner...
