About the Interval of Sculptra Sessions, Is Shorter than a Month Between Sessions too Short?

i'm 33 years old~ i had sculptra injected on my cheeks 3 times~ first in January 28 and second in march 2 an i got the third one just 2 weeks later after the second. because i couldn't notice any change since the first injection, so i hate to be waiting. my doctor was reluctant to do it , but i insisted. now i'm so worried about the side effects. is it too risky that the interval between each sculptra session is shorter than a month?
