Clear stuff, what is it?

So I had my period early this month in cycle day 24. Normally mine are 33 days! It lasted 4 days like a normal period.. Technically I was supposed to start 2 days ago. Since then, I had some cramping and pressure down there. I woke up today and was really "wet". Wtf is that wetness? Never had it. No clue what it is? Boobs don't hurt. Only thing is I can constantly eat and sleep (like I was on my period)!!! Hmm. Took a test 3 days ago and it was negative?
