I really hate when my period is late..

So I was supposed to start yesterday but haven’t...ive been late before!! I’m really really bloated this morning and sort of nauseous!! Last night I had a slight head ache which I usually get right before my period but still no period. And I don’t wanna give my hopes up this time thinking I’m pregnant...I hate when my body does this to me. And ik I’m not pregnant bc this has happened before..and got my hopes up. Ughh this is so irritating...anyone else experience this?
