Should I update my period date?

I should get my period tomorrow and usually the day before I get cramps and pee about 10 times per day (normal for my period) but I haven't had any symptoms as getting my period I only had cramps a few days ago and that's it. Btw I'm afraid to take a pregnancy test. :( and get a BFN. So should I edit my period date and push it back if I don't get it tomorrow? ​
