In theory your pad is only there to keep your saddle a little cleaner when you ride. If your saddle fits properly a thick pad is not needed (or even a good thing).
As long as your pad is still functioning with out clumps or bumps it is fine.
Now....having a saddle pad issue, I say you can never have enough saddle pads so for sure you are in need of a new pad.

Monthly? You really only wash once per month?
