My phone's not good enough to see the pica, but can you see a line?
The first day I did a test on the evening and I could see a very, very faint line. DP couldn't see it at all.
The second day I did a test in the morning, I could see the line again, DP couldn't. A close friend who was staying thought maybe an evap line.
Went and got an early response test, and tried again later that morning, so not with FMU, and got a clear line.
That faint line is now a lovely 2 year old having morning snuggles :)
If you're not sure again today maybe try a more sensitive test if possible?
(I forget which brand the last one was, sorry, but first two were clear blue, second one different brand, possibly boots own brand? Was specifucally for early testing abyway)
