Clear positive on one step but negative frer?

[Pepperlypue]

Has anyone else had this?

I got a faint(ish) but obvious positive on a wide strip one step test last night then even darker this morning with fmu but the frer (same wee) was negative?!
They're definitely the 6 days early ones but they're from amazon.
I have no idea where I am in my cycle as I have very irregular cycles due to PCOS.

Anyone else?
I've had months of awful indents on FRER and now I've got blanks 🤣

I have PCOS too although reasonably regular periods (around 6 days variation a cycle and always the same length luteal phase so once I’d ovulated u knew when I’d be due) - the FRER didn’t pick up things for me until the day I was due or after I was due. With my DS I took one 2 days before I was due, it was negative, also negative on the day I was due and then 5 days later I took one got a faint positive and then tested the next day to be sure and got a stronger one. With 2nd baby, I tested 2 days after being due and got a positive.

I’d say try again in a day or two.

Thank you for replying!
I'm going to go the chemist tomorrow and get some from the shop rather than amazon and do one Monday morning.

I have a ' no bleed scan' on Monday to start ovulation induction so will see what the frer says Monday morning and go from there.

I've had another positive on the one step this afternoon as well so I'll be shocked if they're wrong! X
