First period tampon question?

i am 14 and just got my first period yrday. i am on birth control (DONT ASK WHY A 14 YR OLD IS ON BC!!!) so itll be regular. my next period will be during camp :P so i should learn to use tampons so i cna go swimming. my period i cant tell if its light or regular. there is most of the blood stuck between my legs so not too much on my pad. anyway i wanna use tampons but all i have are regulars. will this be ok? and i have fingered myself efore and it goes down and is mushy before going up. is this ok? thx! :) btw i hate pads!!! :p
