15 Years Old - Shedding has started. :S

[Mat18]

Hey everyone.
I'm 15 and i'm on a few things right now.
I started 5% Rogain in Feb and after a month or so i noticed my ahir wasnt falling out as much.
i have been taking it since then.
i have been on propecia since about april. and once i started propecia i really started to notice very minimal hair loss.
i was very happy with the combined results of the rogaine and propecia. i even noices some growth around my hairline.
now i'm 5 months into using rogaine and 3 months into propecia and i am noticing my hair falling out more.
i see more on my pillow and more in the shower.
is this a case of shedding? and also does hair fall out more during the summer?
and if it is shedding how long can it be expected to last.

(sorry for asking such common questions but i read through a couple other threads and didnt really get any good ansers._

Aren't you afraid of finasteride side effects at your age :O?

im no doctor but if he's old enough to get Male Pattern Hair loss then he's old enough to take Propecia.

That rule does not apply in every case. In extreme cases, male pattern baldness can begin in the early stages of puberty.

but the hair specialist i went to said she has prescribed it too many kids any age.
and really i havent had any sides as of yet.

how long could this shedding last?
