Explanation??

Okay so I’m 10 days late so I decided to take a test just in case. It came out negative (right? Lmao just making sure I’m not like blind here)

Anyways the test says I’m negative.. but I’m still 10 days late?? I did just finish a tournament (4 games in 2 days) so I keep telling myself that maybe I just overworked myself etc. but usually I’m on time give or take a few days. Should I be concerned bc I know false negatives are a thing...

Any advice is helpful❤️
