Girls I need some advice!

So my period is suppose to come anytime this weekend, yesterday while I was at work i had these light cramps & when I went to pee I saw a little spotting & i thought that my period was already here & I wore a pantyliner cause it wasnt that heavy yesterday & i thought that today it would be my period period day BUT SURPRISE! When i woke up this morning the pantyliner was clean as hell & I checked my cvm & it was veryyyyy veryyyyy creamy & in medium amount... so wat could this be?
