What is going on?

I had positive OPK on the Saturday and Sunday but it has said ovulation was the Thursday when I had negative LH tests? 🤯

The shift in bbt looks like ovulation has happened when the app says Lh tests are unreliable really as they only detect a surge in LH but ovulation can fail to happen and the body try again It's likely you had a short LH surge on Wednesday and ovulated Thursday hence the shift in bbt
