I've lost the plot but is there a line?

[Rainyshowers]

I'm 15dpo based on opk peak but did get some more ewm 3 days after so maybe had delayed ovulation. However I only had sex on the Saturday when it was peak opk. Today I used a frer with fmu and it looked blank so took it apart (yes I know!) and got this line. Any hope left or am I out? I can see a very faint line I think.

I can see it but wouldn’t get hopes up based on it simply because you took it apart. Good luck trying again in a day or so for BFP

I can see something very faint but no colour

Can see one on the second pic

Be very careful of taken-apart FRERs. They can produce quite horrid dye runs when opened. I had an opened one last month that was much darker than either of those but was definitely negative. I wouldn't trust an opened one.
