Yesterday I woke up fine and had no blood in my underwear. Then went to breakfast and was fine. My cousin (24), aunt, and cousin (3) were waiting downstairs for me to get changed into my bathing suit ( we were going into the pool) and I pull my pants down and poof! There it is. My little cousin (3) was calling me so I had to put in a tampon quickly... mind that I am 13 and have never actually had to use one. It was so uncomfortable for 2 hours because I didn’t put it in all the way. Has this happened to you?
