Help?

So I always have heavy irregular periods. Well I started yet it was so light that it wasn't even on my pads. Only present when I wiped. Yet today (glow says it ends in 2 days) I woke up to so much blood it was like I just started. So is it possible that this is actually the start of my period? This doesnt normally happen. I mean I have been stressing a little (but never effects my period like this). Thanks in advance!
