Early/late bbt

Okay so usually I will wake up at 6:15am and always temp then but last night I didn't go to bed until 6am I took my temp just before and it was 35.9 and I took my temp when I woke up at 12pm and it was 36.7 , would it be okay to use one of them on my bbt chart or should I just give it a miss for today ?
