When to temp check?

Christine

I just track my fertile days/ovulation with the app and sticks. When do I temp check? I’ve never checked my temp when TTC but I think that’s where I’m going wrong we have been TTC for almost a year and I feel like I’m always off by just a few days since the last couple months my period has been late 2-3 days. Any advice and help would be greatly appreciated on when to check? Time of month, time of day, etc???
