evaporation line or positive pregnancy test

My boobs have been sore for over a month. My boobs have completely changed. I have a few more pregnancy symptoms but I’ve been taking test and they all come out negative until this one came positive.

I’m not sure if this is evaporation line or a positive pregnancy test. I do know evaporation line is colorless. I see a little bit of blue right?? It was negative at first and I looked in the trash can a few hours later and this happened.. I’m not sure if I have low hcg and it’s having trouble picking it up.
