Hey PC good to see you round these here parts again.
You're not going to hurt anything if you continue. Your system had been in ketosis for a good while. How much will it affect your cleanse? It would depend on what and how much you ate but even knowing that there really is not going to be any hard answers. What's done is done and at this point I would say roll with your intuition. If you decide to continue figure adding a few extra days if you had a particular goal.
