If you have several PSA tests and know the dates along with the results.... Sloan Kettering has an excellent calculator available to see what your doubling time is. My oncologist at Mayo uses it. Although there is no set doubling time at which you should "act"; I've found there is somewhat of a consensus that you should take action when the doubling time reaches 10 months. (I am not a doctor. Just my observation)

Thanks again everyone for the feedback. I finally heard back from my PCP today. His response that my second result was slightly lower/stable is good and may be my new baseline. Said I should come in to test again in 2 months. I agree with the retest part, but I replied (this is all on mychart) that I would like to discuss the results further as I am more concerned with the rise than the actual number. I have set up an appt (video) to talk to him Wednesday. I am still waiting to hear from my urologist. I mostly need to talk to him to get his thoughts and so he can refer me to another urologist. This is out of his specialty zone. Yes, as a urologist I am sure he understands most of it, but all of his time is very focused in one area. I would personally like as a minimum follow-up an actual exam by and discussion with a urologist.
I had found the Sloan Kettering tool last week. My doubling time is about 7 months and my PSA velocity is slightly over 2. (Using the 2.5 number). Before this last reading my level was pretty steady at around 1 for years.
