Can you develop resistance to blockers like Cyproterone Acetate?

A blood test I took in October said my Testosterone levels were nicely at the bottom of the female range, and I felt fine.  I haven't changed my dosages since September, yet these past few weeks, and the past few days especially, it really feels like my Testosterone is rising.  I'm even starting to get physical effects.

I don't get how this can happen when I haven't changed my blocker.  Has this happened to anyone else?

I have never heard of resistance to test blockers.
