i've been having cramps for the past few days and i knew i was going to start my period soon but i was hoping not today. which just happened😒 and i'm going to a football game!! help! what do i bring with me?? the bathroom are gross there☹️☹️ my cramps are terrible also☹️

UPDATE:

i didn't end up going to the game. right before, i was feeling nauseous and like i was going to throw up. i didn't eat anything weird or do anything to catch a sickness, but my stomach hurting plus my terrible first day cramps were too much and i stayed home to lay in bed. i feel terrible and i've thrown up a couple times. is this normal? i've never thrown up on my period☹️
