Do you carb count? Did you take your blood sugar before lunch & before injecting your novorapid?
If you are taking in carbs to correct a low blood sugar, you shouldn't bolus for those carbs. That does however depend on you taking in just enough carbs to bring you back to target, rather than go all the way over to 15. A good way of doing that is to treat your hypos with a boring hypo treatment - 3 or 4 dextrose tablets. Seems like the baguette and marmalade was over correcting the hypo.
However, as you have had two hypos today, you are vulnerable to hypos, so I would be super cautious about correcting your hyper and try to do that only with a meal.
