Confusing Period, advice please!

So my period was 9 days late and I was having all these symptoms. At around 9am on day 10 I had really light spotting that stopped. But the next morning I was bleeding bright red. It’s WAY lighter than normal. Typically by this time I would be using a super tampon, but the flow is so light I really could get away without using one. Could this be a sign of pregnancy? Or is this just an odd period? There aren’t even any clots, and I always get clots. Help, please!
