I am on a week long school trip in Disney, I have only the clothes I brought which are jeans, I got my period yesterday and I have to wear the jeans when going with the group tomorrow and im scared of leaking, I wear pads, only have access to pads, and thank god for my mother accompanying me on the trip, so I need ways to prevent leaking, I have a regular darkish pair of jeans and 2 light jeans, they are new jeans not worn and i really don't want to leak through the first time wearing them, please help as soon as possible
