BBT/LH confusion!!

I am new to tracking bbt. My natural cycles app (connected with Oura ring) said this morning (3/5) I was in my peak fertility (all LH strips were negative today)- my peak ovulation was already detected by the strips and clear blue advanced on 3/2 and was high LH until 3/4. Today everything was low (except on my natural cycles app)

Today my Natural Cycles app is continuing to say high/peak fertility even though the strips say otherwise. Can anyone help me better understand this? I am so confused and still learning. This is month 4 TTC.
