The pregnancy process is formed by a mature egg in the fallopian tube combined with sperm. Sperm can survive for about 24-72 hours in the female reproductive tract, while an egg is fertilized only about 24-36 hours after ovulation.Women should first determine their own menstrual cycle before testing. The algorithm is a cycle from the first day of menstruation to the day before the next menstrual period (the first day of the first blood day). Most women ovulate in the next menstrual period. The first 14 days or so, so 2-3 days before ovulation and 1-2 days after ovulation is easy to receive pregnancy, that is, 4-5 days before and after the ovulation day is estimated to be susceptible to pregnancy, so it should be tested regularly after starting the test.Model Number: Ovulation Test StripItem Type:Feminine HygieneStage: Pre-pregnancyFragrance type: no fragrance typeIndependent aluminum foil bag packaging (with desiccant to protect against moisture)Colour:PinkMaterial:Aluminum bagsSize:10.5x5.5cmPackage Contents:1 pack x (90 pieces) Ovulation Test Strip
