Does anyone know whats happening to me?

My periods are regular. But I missed it for a whole week. So yesterday I took a pregnancy test and got a very faint positive. But this morning at around 2am I started spotting light pink. Then at about 8am it was bright red and almost period-like. Now it seems to have stopped all together.

I'm feeling really nauseous and extremely crampy still though.

I'm so confused. Does anyone have any idea what's happening?
