Nipple Piercings after Breast Reduction, when is it safe?

It will be exactly one month after my breast reduction surgery tomorrow and my breasts are healing great. I can sleep on my side and even go braless for the entire day without any problems! Soon I want to pierce my nipples and I want to know when is a safe time. I'm well aware of the risks and I'm not planning on getting it until I am advised. Please don't recommend me to call my surgeon. She's out of town for one and also kinda rude.
