Afraid to be excited 12DPO

I need to talk to someone so badly but I can’t talk to anyone close to me (yet!) and I don’t want to tell my partner until I know for sure! Ladies are you seeing what I’m seeing or is it an evaporation line. I took the test jumped in the shower and forgot about it. The last time I thought I would get a pregnancy test I had kidney stones and the symptoms overlapped. The line is only visible on the bottom but not the top!
