Please help! TMI

Sarah • I am a 18 year old, level 8 gymnast & dancer. I want a job as a gymnastics judge & coach, dance teacher,and a physical therapist.
I have a lot of discharge latly, well ever since I got my period. Is it normal to have a lot your first year of starting your period? It's so much it feels like I've like peed my pants or something. What could this be?
