First period

Can someone help?? I’m 14 and we’ll what I think I got my period but it’s brown and really light and it’s started on the 8th and it’s now the 11th and I haven’t had ‘blood’ or the brown one I’m not sure it it’s my period or it’s it’s brown discharge (a bit tmi) but when I wipe its rend but not a lot of it, I’m worried cause i don’t know if it’s actually my period
