a positive and a negative with same sample?

[hopeforamirac]

Hi all
im currently on cd20 i usually get my surge day 21.

i tested using a tesco own ovulation and it was clear positive so did a cb digi with same sample and it was negative.

any idea's whats happening as they are both 40miu so you would think they would both be positive???

I don't know why, but i'd suggest you start bd-ing anyway just to be on the safe side x

maybe the clearblue was faulty?
