Fertile week possible tmi

So according to glow and the my period calender app today is my most fertile day. For the last 3 days I've had a lot of egg white stretchy cm and when i checked today it's gone and I've a bit of white creamy cm. I'm so confused! Am I not ment to have a lot of ewcm today ? Does this mean I'm not fertile anymore and I've already ovulated ? Please help me by giving me ur opinions and not just reading. Thanks very much xx
