My last pd was on 11-9-16 i'm supposed to get my pd on 12/6 or 12/7. took a test and negative. is it too early to test ? what's going on? thanks !

Yes: Not sure why you're getting another PPD <1 month after the last one which was negative. Unless you have a history of TB yourself, you're taking care of TB patients at home, or you're being exposed to people TB or those a high risk of having TB (e.g. working with the homeless, incarcerated, etc), there's not a reason to get another PPD. The risk of another PPD is low but it'll likely be negative.
