Clear blue vs opk??

Hi All,
Just wondering if any pro ovulation testers can shed some light on this.

Testing mornings with clear blue advanced and then afternoon/evening with wondfo opk.

Yesterday morning was 2nd day flashing smiley on CB.
Afternoon (fairly dilute urine) opk negative.
Evening (concentrated urine) opk positive (pic below)- but checked with CB (same sample) and flashing smiley.
This morning still flashing smiley and opk lighter.

Did I peak last night but not strong enough for CB to detect? Do I take that as my positive or wait to see what CB does?

I found CB very accurate with previously and helped me to pick up a random very late ovulation date which lead to pregnancy before. Not sure whether to trust CB or opk more 🤔

It's so hard to pin point, but you've either just had your peak or youre about to so have lots of sex!

Out of interest why are you using two different types? I'd just use the strips that will make it easier to compare

My cycles have been irregular since I had my Mirena removed so I’m using the cheapies so I can test for longer. I like the reassurance of a digital confirmation though and have found them great in the past. Might have confused things this cycle though! Hopefully I’ll get a static on the CB and as you say, either way DTD!

@Brigg253 Did you get pregnant this cycle?

i have the opposite so I had 6 days flashing smiley then day 7 a solid smiley on 18th March but faint OPK cheap tests throughout
then from 21st March my cheap lh tests are getting darker but not yet peak - this morning 23rd is very very close to being as dark/darker than the control line.
from 21st I’ve been getting flashing smiley on clear blue 🙈 so I’m completely confused.
