CM.. Pregnant or period?!

I usually always always have thick white creamy CM (sorry tmi) every point in my cycle it is usually this way. I am currently TTC and 12 DPO expecting my period in 2 days. I now have watery discharge that I find uncommon. I have had mild cramping, dizziness and slight nausea. I don't know if it's a good sign or just wishful thinking. Everywhere I've looked said it is a possible sign but I'm not sure. HELP?!! What was your experiences
