Lisa • mum of 4 beauties! 3 on earth and one playing in heaven x

I got a 2 pack of clear blue digitals 7 days ago it came up 2-3 weeks, it's now 7 days since... I did the 2nd test and it still says 2-3 should i be worried or can this happen?

Is there Anyone who has has any experience that could put my mind at ease? Thanks🙂
