Confused about charting

Maybe I'm losing it but I swear to god yesterday glow suggested I'd be ovulating today and yesterday was my highest chance of getting pregnant. I went to log my bbt this morning and now it's saying my ovulation day was two days ago (before I even had a chance to log). Of course the new two highest chance days were the only two this week we didn't have sex. Has this happened to anyone else? I'm confused and annoyed.
