A strong positive ovulation test strip indicates that the luteinizing hormone has reached its peak and ovulation usually occurs within 1-2 days, which is a sign that the follicle has developed and matured. After the follicle has ruptured and ovulation has occurred, the ovulation test strip will change from a strong positive to a weak positive or negative result. If a woman is preparing for pregnancy, she can increase the frequency of sexual intercourse within 2-3 days after a strong positive ovulation test to increase the chance of conception. Generally, you can use the ovulation test once a day for 1 week after your period. If you find that a strong positive ovulation test is gradually increasing, you should increase the frequency of testing, preferably every 4 hours. If you compare the test strips and find that the ovulation test results start to weaken and turn weak quickly, it means that ovulation is imminent and you can arrange intercourse. The time frame for ovulation is usually within 24-48 hours after the ovulation test result becomes weak. In addition, during pregnancy preparation, women should pay attention to relaxation, avoid prolonged stress, pay attention to a light diet, eat less or no cold, spicy and stimulating food, develop good living habits, ensure sufficient sleep and pay attention to appropriate exercise, which can increase the chances of pregnancy.
