1. Collect urine in a clean and dry container. Do not use first morning urine. The best time to collect urine is between 10:00 AM and 8:00 PM. Try to use the urine sample at the same time each day. Avoid excessive fluid intake 2 hours before collecting urine. 2. Immerse the test strip into the urine up to the MAX mark line for about 3 seconds. Remove and place the strip flat. Read the result within 10 to 20 minutes. Do not read results after 30 minutes. Normal women ovulate each month. When an egg matures in the ovary, it is released and travels through the fallopian tube toward the uterus. Pregnancy occurs when sperm fertilizes the egg in the fallopian tube. Sperm can survive in the female reproductive tract for 24 to 72 hours, while the egg is viable for approximately 24 to 36 hours after ovulation. Women should determine their menstrual cycle length before testing. The cycle begins on the first day of menstruation and ends the day before the next period starts. Most women ovulate around 14 days before the next period. The fertile window includes the 2-3 days before ovulation and 1-2 days after, making it the optimal time for conception. Testing should be done regularly starting from the expected fertile period.
