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 urine samples at the same time each day. Reduce fluid intake 2 hours before collecting urine. 2. Immerse the test strip into urine up to the marked line for about three seconds, then remove and place it flat. Read results within 10 to 20 minutes. Do not read results after 30 minutes. The insertion depth should not exceed the MAX mark line. Normal women ovulate monthly. When an egg matures in the ovary, it is released and travels through the fallopian tube to 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 remains viable for approximately 24 to 36 hours after ovulation. Women should determine their menstrual cycle length before testing. A cycle is counted from the first day of menstruation to the day before the next period begins. Most women ovulate around 14 days before the next period. The fertile window includes the 23 days before ovulation and 12 days after, making pregnancy most likely during this 45 day period. Test regularly once starting.
