Help I'm confused 🤔

Joanna • Married with 4 daughters and a boy on his way.

Ladies I just took a digital clearblue and it said not pregnant. I saw a lady on here use the same test and get not pregnant then she opened the test and there was 2 blue lines on the strip and I was like wow so I decided to just humor myself and I see 2 blue lines!! What should I do? Is it just what happens or something? I'm so confused. Period is due tomorrow.
