I would encourage you to consider continuing with periodic colonics, perhaps each quarter as the seasons change.
Even if you are not releasing mucoid plaque or other impacted wastes, colon cleansing helps your body to eliminate toxins and less visible waste matter that is inside all of us just as a result of pollution in our environment.
As a practicing colon hydrotherapist it's not often that I treat a client who doesn't eventually pass a great deal of old waste matter. Even at your age most women tend to have a lot of old stuff in there, although a lot less than the typical client tends to have at 38 or 48.
Are you taking enemas at home to help keep your colon clean?
