It is relatively normal for the ovulation test paper to be negative during the ovulation period, because sometimes women may encounter interference from other factors, such as the quality or improper use of the test paper, or the woman's menstrual cycle is relatively unstable. Although this situation is relatively common, it does not mean that a woman cannot become pregnant during ovulation.

1. Carry out regular monitoring: If you use ovulation test strips during the ovulation period and the result is negative, you may consider regular monitoring. You can use David's ovulation test strips or David's ovulation test strips sold at pharmacies, which can be tested every morning when you wake up and record the test results. Through regular monitoring, you can understand your health status and take appropriate measures at the optimal time.

2. Increase nutrition: During ovulation, women’s hormone levels increase, which may lead to increased appetite. If your appetite increases during this period, you may consider increasing your nutrition to help you get pregnant. You can meet your body's nutritional needs by consuming protein-rich foods such as fish, meat, eggs, and beans.

3. Maintain a healthy lifestyle: During ovulation, a woman’s hormone levels rise, which can lead to mood swings. If you experience high mood swings during this period, you may consider taking steps to reduce your mood swings, such as practicing yoga or meditation, or seeking psychological counseling.

4. Take appropriate measures: If you use ovulation test strips during the ovulation period and get a negative result, you may consider taking appropriate measures to increase your chances of pregnancy. You can have sex at the best time and use condoms or other safety measures to protect yourself.

A negative ovulation test strip during ovulation does not mean you cannot get pregnant. If you take appropriate measures during this period and follow the correct testing methods, you can increase your chances of pregnancy. If you are still confused about pregnancy, it is recommended that you consult your doctor or a professional fertility counselor.
