May be tmi

I took a test a few days ago and someone tweaked it thought it may have been a vvvvfl. Well today is the day i am supposed to get my period. I am like clock work with a 29 day cycle. I start on the same day every month. Well, I noticed my cm is different this month. So I may buy a test and take it tmrw morning. But it's not creamy. It very wet and clear like egg white consistency. I've been pregnant 2 other times and miscarried, but I'm worried/excited. I don't want to get my hopes us. But I know this isn't normal cm for me on the day in supposed to start my period. Any thoughts?
