1st time using CD Digi OPK - CD13/25 still no +???

[Petal]

Hi, I am using CB digi OPKs this cycle for the first time (previously used FR OPKs) and today is CD13 of my regular 25 day cycle. I have just tested and still have no positive reading, which I was expecting to get by today as using FR OPKs I estimated my OV to be on CD14. I don't get strong OV pains so just use OPKs and monitor my CM, which today and yesterday has been clear.
We BD this morning and will do again tomorrow just in case..

Has anyone found the digis to be more/less accurate or 1 brand more/less accurate than another??

Should add that I started testing from CD8 so very unlikely that I missed the surge....

UPDATE - tested again at midnight last night and got a .
had bought the tests in bulk off the internet and was worried I got sold a dud - but thankfully not!!
