Will Spyronolactone stop me from growing?

Hi, I am a MTF , and I have been taking spyronolactone for about 6 months now. I'm sixteen now and I started taking hormones the summer of '10. I struggle with my height greatly, I'm about 5'10"-5'9" and I was wondering if this medicine will stop me from growing anymore. I know it blocks testosterone, but I really want to stop growing. Thank you for your help <3.
