Not accurate?

I'm new to Natural Cycles but not BBTing. I'm not sure how I feel about the Natural Cycles app yet. It's still waiting to confirm ovulation but my temp is all over the place these last 3 days are my second temp in the morning before moving or getting out of bed, drinking or anything basically within 5 minutes of waking up. My Peak surge was on the 24th but this isn't showing if I've ovulated. Any thoughts? I do wonder is it possible as I'm waking up cold my temperature isn't raising? I have woke up the past 2 mornings with no covers on (laugh as it's my dog stealing them) so my upper body is chilled.
