Traveling while on period

Hi! I kind of just need positive comments regarding traveling while on my period. Typical I get sick and by sick I mean nausea. After my period ends it lingers. I'm freaking out because I'll be on an airplane in a whole new state while on my period and feeling these symptoms.And when I feel these symptoms, I get extreme anxiety, it hits me in my gut.And i'm pretty terrified. I know it sounds silly like a small problem to have.But when i'm feeling any type of sickness while traveling, it is such a big deal.It will ruin everything for me.
