Evaporation lines or positive pregnancy test??

Mikael • Mother to beautiful baby boy 💕 20

Okay so yesterday my friend & I both took pregnancy tests. When we read them they all said negative. However, this morning something told me to go look again. (Btw I’m 2 days past my period) when I looked at mine there was a small faint dark line on both tests. When I looked at my friends she didn’t have any. I know there are such things as evaporation lines, but could this be a possibility of pregnancy? With my first born son, I tested positive one day after my missed period that’s why I tested so early. I’m hoping for my rainbow baby🤞🏽🌈
