What time of day should I do my Hertility test?

Test in the morning, within the first few hours of waking, after fasting at least 8 hours overnight. Water is fine after fasting. Some hormones fluctuate throughout the day and can be affected by food intake, exercise and stress, so morning collection gives the most reliable results.
