confused 🤔

I was 6 days late for my period got it for 3 days and I'm normally on it for 5 days it was way lighter than normal been off my period for a day now just went to the bathroom and when I whipped it was light pink ? The second day on my period I woke up throwing up and was sick all day still always nauseous just no throw up. 
UPDATE: I tested and got BPN but I was off my period for a day then just started bleeding again this morning super light but I just don't know what's going on 😐
