Clear blue advanced ovulation test

I used a clear blue ovulation test yesterday and it was flashing, just like 2 pervious days.

Because I’d had 3 days of flashing I got another box just in case the digital stick was faulty and then I got a blank and also a flashing.

On 3 different sticks I’ve had blank, flashing and peak all with the same wee sample. What on earth do I go by?!

This IS NOT my first time using them!!

I didn’t once state that so thanks for jumping down my throat
