I've a question can you track Ovulation If You Don't Wake Up at the Same Time Every Day??? please tell me

Every guide about basal body temperature seems to say the same thing which I see every where like take your temperature at the same time every morning which I do. TBH I wonder how many people can actually stick to that every single day ..Some mornings I usually wake up early and other days I just sleep in and don't even talk about weekends they are completely different and if life gets busy my whole schedule goes out of the window 😭and it's one of the reasons why I started looking into wearables like tempdrop rather than relying on those irritating alarm evey single day every single morning 🌞

Also if your schedule isn't consistent either then how do you approach tracking.. Do you like notice your charts becoming easier to trust, or does it still take some getting used to? Please lmk
