Memory is a poor judge of weeks. A log is better.
Each day, note whether you took the capsule, the time, digestive comfort on a 1 to 5 scale, any gas or bloating, bowel habits, sleep and stress. One line a day is enough.
The page suggests a realistic window of several weeks, so review at weeks four and six, not week one. Look at trends, share anything worrying with your doctor and decide well before day 60 whether to keep going or ask for a refund.
