What happened to the early pregnancy test paper and ovulation test paper

Early pregnancy test paper is suitable for detecting the level of human chorionic gonadotropin in women's urine. In 7-8 days after sexual life, eggs and sperm can combine to develop into fertilized eggs, and human chorionic gonadotropin levels will rise. When urine reaches a certain concentration, it can be detected. The ovulation test is used to detect the level of luteinizing hormone in urine, so to detect the specific ovulation date of a woman. Pregnancy is only possible after sex during this period, and pregnancy is not possible even in the same room because the ovaries are not able to ovulate at the rest of the time. Both tests can be tested at home.
