Tmi cm pic. Late period snot like cm

Three days late for my period, all negative tests so far. Had clear watery cm but today it is snot like. I’ve included a pic. had cramping the last 4 days like I’m going to start AF. What’s going on 🤷🏻‍♀️🤷🏻‍♀️ I know you can’t tell me if I’m pregnant just wondering if anyone else went through this.
