tampons on a light flow??

i want to wear a tampon for an event coming up because it’s more comfortable and convenient but my follow is quite light and i’m not sure if i should use one. i can use them on the 1st, 2nd, 3rd, and 4th days (of 6) as i have a more medium flow but should i try on the fifth day? i’m worried it’ll be too dry to put in
