Clearblue Advanced OPK

Hi ladies!

So hoping some of you seasoned pros might be able to help... I’ve started using the Clearblue Advanced opk’s after 6 months TTC. The last 3 months we used a Tesco opk that never showed I ovulated.

I finally got a high reading, but it’s still showing a high reading on the 5th day 🤔 and my period is due anytime between Wed-Sat next week (I have short cycles between 21-23 days).

So question is... shouldn’t I have had my peak by now? And if it doesn’t show a peak does that mean I haven’t ovulated? Has anyone got pregnant just from having a high result?

Sorry for all the questions! This is all such a mine field and just feel a bit lost about everything 😓

Any help would be massively appreciated!
