Lines on cheapy tests but not CB?

[scaredandsque]

I am only 10 days past ovulation, the only day I had sex this month was on Wednesday the 12th of July, and my period is due on Tuesday.

I haven't been feeling right, so tested yesterday and negative.

Then had bad cramps today so tested again and result is what I got below.

Very faint lines on cheaply tests - 25 ml.

But negative on clear blue early detection which I think is 10 ml. So doesn't make sense.

Lines are very faint so just not sure if they're even there. They came up almost instantly and no evaps or lines on ones from yesterday. Just confused as negative on clear blue.

Does anyone have any experience of this?

I hate those clearblue ones - never got a strong line on them even when I got 3+ weeks on digital! I'd wait a couple of days and test again with a first response or another pink dye one x

Definite lines there but like @moosey89 said I do not rate clearblue early tests at all. Gave me nothing but evap lines and other cb tests have took time to show lines so I'd also say test again with a first response or boots early test x
