Clear blue evaporation line?

[Nursemama001]

Hi everyone! 😊

Just wanting your opinion on this. I took a clearblue test this afternoon and it looked negative at the time. I’m not sure if I left it the full amount of time as I didn’t have my phone with me to check the time. I was rushing out of the house so checked it when I came home a few hours later and it looked like this. Do you think this is just an evaporation line?

Im still breastfeeding my 10 month old so my periods haven’t returned yet. I had what I thought was a stomach bug on Tuesday night but the nausea hasn’t went away which is why I tested.

Thanks in advance! X

Your pic hasn't posted. I'd do another test though.
