Probably a bit higher than you want especially if it is higher than your last test.
It is easy to become complacent and for the diet to slip so revisiting your carbohydrate intake and reducing portions and maybe being careful of those 'extras' that have snuck in more regularly than they should.
Some more strategic testing of what foods you can tolerate may pay off in that you can cut out some of the culprits. So test before you eat and after 2 hours and if you see more than 2-3mmol/l increase or more than 8.5mmol/l then the meal is too carb heavy so make some substitutions or reduce portion of the high carb food. Making a food diary alongside your reading would help to see where you could make some savings.
Diabetes is a condition where your tolerance can change over time so adjustment may be needed.
An HbA1C of 52mmol/mol is not desperately high so some tweaking of your diet should help.
