Clear blue digital ovulation flashing but faint cheap tests?

[Jr9901]

Has anyone used the clear blue digital ovulation trackers that give you a flashing and static smiley face? I have flashing smiley face for the last two days which means high but not peak time but the cheap one step tests there’s barely a line there.

Clear blue Digi OPK look at both oestrogen and LH. The flashing smiley is detecting the rise in oestrogen that comes before the LH surge, the strips only test for LH. The static smiley is your LH surge and thats when the strip should be darker. Hope that helps!

Aha that makes sense I didn’t know this! Thanks :)
