Regular tampon with light flow?

Emily • Hi! I`m Emily! I play 5 different instruments! And I also sing! I love hanging with friends and my boyfriend
Do my friend want me to go swimming tomorrow with her, but I have my period, and it's a light flow, it's is the 4th day of my period. I don't know if I should use a regular Kotex tampon or not, only Because I don't have any other ones, I know about TSS so I feel like I shouldn't do this, but if someone could please comment, i would really apprecate it!☺️
