Period is due today

I’m suppose to get my period today. My period have always been 7 days. In two days I’m suppose to go on a 3 day kid free all expenses paid trip with my husband. Our first trip alone since our honeymoon almost 5 years ago. Why does my body hate me?? I’m still regulating since having the baby 19mo who. This will be my 4th period so I’m hoping it’s late but if it is I know I’ll be constantly worried on the trip about if it’s coming on. Crappppppppppp.
