FREAKING PERIOD

of COURSE my period starts the DAY BEFORE i’m going to my boyfriends house. i really don’t want to be on my tampon the first time i’m going there and meeting his parents because 1. bc i don’t want to stink. 2. bc i’m going to break out with a TON of pimples and 3. i’ll be moody. i plan on never being moody with him for a while bc he’s the sweetest to me.. but it started also twO DAYS before i’m going to go to the lake with my family to swim.. the problem with THAT is thaT I CAN’T PUT TAMPONS IN😭 and everytime i have to swim in situations like these my mom forces me to put a tampon in and i really can’t. like EVERY singe time i try.. i end up passing out, on the floor. idek i’m just really stressing out rn. this is like the worst time my period could ever start. what should i do?
