contradictory pregnancy tests

[deeplybaffled]

hi....hoping someone might be able to help, as even more baffled than average at the moment!

been ttc for a few months now, AF was a few days overdue, so tested (FRER) yesterday and BFP :)

Fairly stunned, so did another test today (Boots) and that was negative.

which is more likely to be right???

not sure whether to celebrate or cry :) / :(

anyone had anything similar?

First response. I had 2 bfp 2 days in a row with it. Took a clear blue the 3rd day and it was bfn. My test of choice is first response always for that reason.

hmmm. am about 3 days over when AF was due, so would have thought both could pick it up?

will try again in the morning and keep my fingers crossed.

going for cautiously optimistic if others have had good experiences of FRER over others......
