There is no way to tell.
You might be fine, but being consistently above 15 with T1 holds a small risk for DKA. Which is an emergency that can land you on the ICU very quickly.
I would try to get hold of your nurse sooner, and at least buy some ketostix so you can check for ketones should you feel unwell.
If you get any symptoms like nausea, belly ache, vomiting, a funny smell on your breath (pear drops, acetone), or a strange way of breathing, don't waste any time but get to a hospital.
With such a long time between the test and hearing the results, chances are you'll be ok for another 2 weeks.
But be aware of the risks and alarm signs.
Good luck!
