Open Question: I'm going camping and canoeing this weekend, but I'm on my period. Any advice?

So me and a bunch of friends are going camping this weekend, only I'm on my period. The good thing is, we will have a trailer. So I think I'm good but we're also going to be doing some canoeing. I think I'd be fine with a pad but I'm afraid that I'll fall into the water or that my friends will want to play in it. My mom is iffy about me wearing tampons and today she made up the excuse that we don't have the money for them. Even if I offered to pay for them she'd still make up an excuse. But do you think I'd even need them? And how do I deal with my period when we go camping?
I asked my mom and she got mad and now she won't talk to me.
