Charting BBT and confused!

[daydreamdaisy]

I'm charting my BBT every morning on waking, times are really consistent. I was predicted to ovulate around CD18/19, and all my symptoms seem to align with this (EWCM which has now gone, cervix I think) however this app refuses to say that I've ovulated!
It keeps saying it needs high temperatures so I'm worried there wasn't enough of a shift or I might not actually be ovulating? Thoughts?
My temp has been higher for 4 days, but not as high as it has been in the previous cycle.
Anyone a BBT charter who's had similar?
Have attached chart for ogling

Keep going. Think it needs at least three days of higher temps (at least being the operative phrase). It really isn't helpful except further into the cycle.

There is a shift so don't get worried. Relax.

It will be confused because of your CM. It needs three higher temps after ovulation to confirm but also looks at your CM which should disappear from being fertile (egg white/watery) as soon as ovulation has happened. Because you’ve logged fertile CM after a temp shift it won’t think youve ovulated then until it gets more info x

Thank you! I had a problem last cycle with fertile CM after a clear temp shift so that sounds like it could still be a lingering issue! I'll try and relax and see how the chart carries on, at the moment I'm a bundle of neuroses
