mmol is 9.2

Hi and welcome.
Metformin has no effect on the carbs, starches and sugars in your food. What it does do is limit the ability of your liver to make glucose itself from stores and top up your BG with it. It should therefore, over time, reduce your HbA1c a little as a result. You probably won't see anything from a fingerprick test - especially after food - that you can definitely say was due to metformin.
When you fingerprick test you should be able to work out how well you handled the carbs by taking a baseline test before you eat, and then a second test after two hours, by which time your body should have dealt with most of the glucose from the food. You're looking for the two readings to be no more than 2 mmol/l apart, and for the second one not to be above 8ish.
Taking a reading about 45 minutes to an hour after you've eaten is likely to be around the high glucose point. I can get from 5.3 to a 9.6 from one small latte after 45 minutes: but it's back to 5.3 by an hour or so. So it's possible the 9.2 you saw is just the impact of the banana, which has plenty of sugars in it. Hard to say what the actual effect is without the inital test, though.
