Positive pregnancy test or evaporation line?

in Pregnancy
Hi,
I’m late for my period and have been experiencing brown discharge in place of it.

I’m late for my period and have been experiencing brown discharge in place of it.
So I took a clear blue pregnancy test yesterday and then two this morning one being a first response. Which appear to be positive but I’m not 100% sure.
I had a blood test done last week which was negative so I’m very confused and am unsure if these are are correct or just evaporation lines..
Can someone help please! Do these look like evaporation lines?
