BBT post ovulation

[JJ1989]

I’ve been tracking my BBT for a while now. I always ovulate on or around day 18, which is when I get my peak on my ovulation test. Normally at around day 20 my BBT temp will rise. This month it’s been slightly different and whilst it has risen, my temp post ovulation as been lower than usual. Normally it was would be in the 36.6 - 36.7 range and instead it’s been more around 36.4/36.5. I’m wondering if I’ve ovulated or not, but would appreciate some advice on here! I’ve attached my chart :)

The rule of thumb is that ovulation is confirmed when you have three consecutive temps higher than the previous six.

CD21 looks like a contender for ovulation if tomorrow's temp remains high, but unfortunately you seem to be lacking 3 of the 6 previous temps so FF will struggle to pinpoint it. When it comes to BBT, consistency is key and you've missed a fair few temps at the most crucial time!

Thanks @Juno231! Yes unfortunately I had a busy weekend socially (admittedly a bit hungover on Sunday) so a few key dates got forgotten!

I think if tomorrow is high then assume it was cd20/21! Temp wise I'd say CD21 but it seems a bit late after a peak OPK on CD18.
