So I have this 3 day "survival" camping trip in August coming up. We're supposed to be doing like a 10km hike (there's also a really steep hill we have to climb almost everyday), one day we have a 5km canoeing and swimming trip (mostly canoeing), rock hopping (jumping form rock to rock in a river), and there's also another day where we camp in the bush with no toilets or anything. The problem is I'm most likely going to have my period

Please give me advice on how to handle this - especially the canoeing and swimming side 

Thanks xxx
