On my period and first date. Plz hlp.10 pts BEST answer!!?

Ok so I'm goin on my first date and it's at an arcade type place and I just got my period. I don't want to keep going to the bathroom and I don't want to carry a purse in a arcade and I think he's going to catch on if I keep going to the bathroom. So should I cancel or still go. And if I should still go what should i do?
