I just took a pregnancy test

I actually took it way earlier like 4 hours ago, I looked at it within 5 minutes I think and the was no double line, I left to the store and came back to find this 😳 I'm happy confused don't know what to do! My predicted period is supposed to start today, I've had not symptoms other than sore breasts for the entire week & a little bit of cramping... Help! 😰
