I'm a day late from my period. I had yellow- like discharge, today it's white/clear, a bit stretchy and clumpy. Is this a sign that my period is coming?

Please see a gyn. U can get a blood pt to know for sure and u will need exam, cultures tor /o infection and a pelvic ultrasound, try to get seen tom or go to the er tonight or tom, if u can't get in to see anyone.
