4 days late, beta <0.100

Hi ladies! I’m four days late, I was so worried I did a pregnancy test (beta HCG) and this was the result:

It means I’m not pregnant, for sure, doesn’t it?

Tnx ❤️❤️

(I’ve started working out last week, 3 days a week. I have also been so sick before my due date. Could they be the reason why my period is late?)
