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. Avoid excessive fluid intake 2 hours before collecting urine. 2. Immerse the test strip into urine up to the MAX mark line for about three seconds. Remove and lay flat. Read results within 10 to 20 minutes; do not read after 30 minutes. 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 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 fertile window includes the 2–3 days before ovulation and 1–2 days after, making it the optimal time for conception. Regular testing is recommended once the cycle tracking begins.
