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 sample at the same time every day. Reduce fluid intake 2 hours before collecting urine. 2. Immerse the test strip into urine up to the MAX mark line for about three seconds, then remove and lay flat. Read results within 10 to 20 minutes. Do not read results after 30 minutes. Normal women ovulate monthly. When an egg matures in the ovary, it is released and travels to the uterus through the fallopian tubes. Pregnancy occurs when an egg in the fallopian tube combines with sperm. Sperm can survive in the female reproductive tract for 24 to 72 hours, while an egg remains fertilizable 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 start of the next period. The most fertile window includes 2-3 days before ovulation and 1-2 days after, making 4-5 days in total when pregnancy is most likely. Test regularly once the testing period begins.
