Ovulation day predictions

Ok soo.. I’ve got a question for u ladies, just wondering if this happens to u and if so.. suggestions, if any??

My Glow calendar says that my peak ovulation day was yesterday but my CM says different. I’ve been really good at tracking it lately and from my understanding(please correct me if I’m wrong, please) when ur at peak ovulation the CM should be in the “raw egg white” stage.. if that’s the case then my ovulation day was almost a week ago, on the 1st exactly, like heavy on the raw egg whites. Lol. So much that even my man even made a couple comments during my birthday sex😜. Anyways tho.. if I am correct about the cm texture and my correct ovulation day is there any way to change my calendar to show my actual assumed ovulation week?
