Need Help understanding Fertile CM

I'm not doing opks this month as I thought I had some and didn't so solely going off cm.

Glow has been pretty spot on with periods and Ovulation the past month. It's saying my fertile period was 24th-30th.

Ive had EWCM since the 26th through to the 30th. The 31st my cm was creamy and not stretch at all.

Today (1st September) i went to the loo and checked and there was sooo much EWCM and cramping.

Going off cm, when would you possibly say I 'ovulated' 😊
