So sorry to hear you're dealing with this, I know how scary it is.
Really early on, the day after my period 'should' have arrived, I woke up to a sensation of wetness. Sure enough there was red blood there. It petered off gradually over the day, never amounting to much. Just like you described, it was red at first and then faded to pink. It's now been two weeks since that happened and everything is going along just fine.
Bleeding can mean a lot of things. In your case, I am fervently hoping it means something completely insignificant. It probably does!
