Clear Blue... false negative?

[DeesGirl]

Hi..
So I think I could be pg (4 weeks if I am)
Lots of symptoms, including constant vile metallic taste in my mouth which I have not had since I was probably abt the same weeks pg with my son(10)..
Food tasting different
Tender boobs, tingly nipples
Feeling sick all the time
Sore back
Sore, crampy tummy.. etc, etc...
Due on my period in the next couple of days.. but.. I did 2 Clear Blue tests this afternoon, first one there was an error, second said 'not pg'
Has anyone else has false negative with with CB? I'm driving myself crazy here.. I definitely feel very different to my normal PMS symptoms..
Any advice on what to do next? Try more tests? If so, which one would be best this early? Or should I just try to wait it out?

Thanks in advance

Was it CB Digi?

Yes I think it was

I think the Digis are pretty reliable.

They aren't a sensitive test and I never got a positive until af was late. .
Try a frer with fmu!!

Whats does it mean i dont understand this can someone tell me

What does it mean

Not pregnant

Deesgirl, use the first urine of the morning for your next test n maybe try a extra sensitive early test usually clearblue or first responce do them

Thanks all.. will give it a few days and see x
