Is there hope?

So I’m supposed to start my period today but it haven’t started yet. I’m very regular so I’m kinda confused. I took 2 pregnancy test last week and was very negative. Is there still a chance I’m pregnant? I’m not getting my hopes up just looking for other people’s experiences. I will take a pregnancy test tomorrow I just haven’t been able to go to the store yet.

Also I usually get really bad cramps a week before my period and haven’t gotten any and that was my first symptom with my last pregnancy.

Thanks for any advice 😊
