Girls advice only please?

Hey, I'm 15 and i'm curious as to whether the amount of daily discharge might decrease as i grow older? At the moment, my doctor has taken a swab (because i have yellowish discharge with an odour that was fishy but due to antibiotics is now salty.. and i have to wear a pad everyday because i have so much) it doesn't seem to be bv because the antibiotics hasn't worked. she said it could be just the norm for my body. basically i was wondering will the amount decrease as i get older? thanks!x
