I might be getting my period during vacation?

I'm 14 and nervous because me and my family are going on vacation together from April 15th to the 22nd. Today is March 12th, and I got my period today. Normally every month I get it around this time (somewhere between the 10th-20th). Vacation is 35 days away so I'm scared I'll get it again while on vacation. Please help what do I do? I have everything I need for my period but I just don't want a vacation that's supposed to be fun to turn into something where I have to have cramps, carry pads/tampons around, not go swimming, be moody, worry if I leaked, etc. I can't recschedule either because we want to be on vacation while it's easter break where me my cousins and siblings have no school. One of my sisters might also be on her period around that time since I always get it same time as her or a week before. She's in her mid-20's so she's used to it but I'm 14 and have only had it for 2 years :( please help. Also my periods are about 5 days but I get brown discharge for another day or two.
