Brown discharge

MyNameIsntImportant

This is not a period. I posted before and 2 girls told me it's my period but it's not. I can wear a tampon in for 8 hours and sometimes it'll cone out dry or light/medium spotting. Sometimes there's red but that's from me sticking a tampon in when its dry up there. On January I missed a period. February i had the same discharge that lasted for a week almost two. I know It's old blood but what the heck is going on with my body 💀😑
