Hello Catherineanne and thanks for posting, 

I am not sure if anyone else will post. Generally if a cervical screening test result shows HPV with no abnormal cells, screening is repeated after a year. So although some people may have developed CIN2/3 in the twelve months leading up to their repeat screening test, there would be no way of knowing exactly when this happened.

Treatment for CIN2/3 is usually to remove it.  I assume you have had all of your cervix removed and that all of the CIN was removed as well, so hopefully this will have been sorted out. 

After treatment for CIN, a test is done 6 months later to look for HPV, this is routine. Most people don't have hysterectomies to treat abnormal cells so they have this test using a brush to remove cells from the cervix. But if CIN is found in the cervix after a hysterectomy, a vaginal vault sample is taken instead to look for HPV. If this is negative then no more screening may be required depending on whether or not all of the CIN was removed. The vault smear is in case there are any cell changes in the vagina as a result of a HPV infection.  

I don't think you need to be overly concerned about the time it took for CIN2/3 to develop. As far as I know it isn't certain that CIN develops through the different grades (1,2 and 3) in sequence or if CIN 2 or 3 just pitches up without ever being CIN1. But it can take years for cancer to develop after CIN does, if this ever happens.
