Lots of us on here have been in the same situation. My PSA was 0.03 for about a year after surgery then started to slowly rise. I had salvage RT three years after surgery. I am 11 weeks post SRT and the PSA has gone down from 0.27 to 0.08. Not the route I wanted to take but there we are.
The variations are small and technically you are still classed as undectable,but it is good your consultant is on the ball.
Thanks Chris
