Hi carina, it's unpredictable sometimes, I'm afraid. Getting a 'spike' of 12.x two hours after eating isn't great, but probably not that unusual unless you're very firmly committed to a strict diet of 'foods that won't spike me'. Finding out what those foods are is part of the joy of diabetes and it's not always that easy. Foods digest and convert to glucose at different rates - some may spike at 1 hour and then decline, others may spke at 3, 4 or even 5+ hours, so you can't be sure that you've always spotted the high point. Remember that a fingerprick test is only a snapshot and doesn't tell you the rise and fall after eating and digesting.
Ideally, we'd all have CGMs (continuous Glucose Monitors) to tell us what's happening but that's not a practical reality yet, so all we can do is be methodical in our tests, recording the details, and seeing if we get a similar response the next time. It can't really be rushed, so patience in abundance is necessary, and you shouldn't lose heart if you encounter the occasional undesirable reading. Have you eaten a mal like this before? If not, it's worth repeating the meal sometime in similar circumstances and maybe test at 1 and 2 hour intervals.
