Clear blue smart countdown?

Danielle
Has anyone taken one of these before? I did a test this afternoon and got a "not pregnant" even though everything that's going on at the moment is making me not believe this test I've taken. 
I took the test apart and I know you shouldn't, regardless of that.. These tests only actually contain one hcg test strip unlike the weeks estimator and after abit or research and emails to clear blue they have said the strip inside does not test for LH like the weeks estimator CB digi test does.
I've read some really terrible reviews on it since buying it saying that they can give false negatives brought at a reduced price today from tescos, I wondered why was so cheap. 
So yeah I cracked it open and in disbelief there's a second line there.. Still waiting on a reply from CB themselves.. Because they state the strip in these tests are for hcg only.. And will show two lines of pregnant and one line if not.. I'm wondering if there's a certain darkness it needs to be for it to read pregnant? 
Has anyone else had this? 
Secondly to all of that.. I tested Monday with CB plus.. And had this result also .. Will post pictures below.. Now can u see my confusion.. I will be testing with cheapie in AM also. 
Monday's test..
