What can I do If I have my period at camp?

So my period lasts 4 like 6 days and my first day of camp is on my sixth day of my period. My counselors are going to know because my mom and I are going to tell them on meet the counselor day which is in like 2 days and I am afraid that it will be embarrassing because everyone will see us. Plus, none of the kids in my bunk are even close to puberty and we get dressed all together. Im scared they will make fun of me. Also, when I have my period, how will I be able to get dressed in front of them? The camp nurse knows and she is going to contact my director for things I can do when we have swimming because I don't wear tampons but my director is a male and I don't like men knowing I have my period. Please help! Camp is in four days! P.S- I am 10 and a half and had my period for four months.
