Shouldn't have too much impact. Can you take bs reading? I went too low on it once or twice as my doseage was too high. Had a hypo and ate tsp of honey which sorted it out. Do you do readings? If so, what's your normal reading? Keep an eye. A hypo is 4 or anything below. If you are worried make sure someone else around, tell them what you've done. You could ring 111.
