I've Been Taking SPIRACTIN For About 6 Years Now...... I

I've been taking SPIRACTIN for about 6 years now......
I hate medication and anything chemical / unnatural but I take it to slow down the growth of facial hair AND control annoying mild skin issues/ milia ......
It works well but I'm always wanting to stop as id prefer not to take it.
I don't take any other medications ,
I'm 37 years old , female and hoping to have kids soon (which is when I'll have to stop taking spiralactone anyway)...

My concern and ultimate question is -
Am I doing any damage?
My health is so important to me-
Can it be causing any short/long term disadvantages ??

PLEASE HELP -
Thank you very much,

Shiri
