How long does it take for the test paper to fade after the egg is released?

In order to increase the chances of conception, it is a very good choice to have sex when a woman is ovulating. However, ovulation occurs inside the female body, so it is difficult to determine the exact time even if you calculate it accurately. At this time, you need to use some testing tools, and ovulation test strips are a typical one. However, some people have questions about the details of use. So, how long does it take for the egg to be released before the test paper turns pale? Let’s take a look below.

Generally, 24 hours after the egg is released, the test paper will become lighter and weakly positive. A weak positive result on the ovulation test paper is during the ovulation period, but it does not mean ovulation. When the ovulation test paper detects a strong positive result, it means that the ovary will ovulate within 24-48 hours, and ovulation is more common within 24 hours. In addition, ovulation usually occurs when the ovulation test paper turns from strong positive to weak positive. That is to say, after using the ovulation test paper to measure a strong positive, if it immediately measures a weak positive, it means that ovulation is occurring. The next day, use the test strip again. If the test is always negative, it means ovulation has occurred, so the test strip will become lighter about 24 hours after the egg is discharged.

How to use ovulation test strips

1. Choose the time period for using the ovulation test strips

For women with regular menstrual cycles, ovulation is usually about 14 days before the next menstruation. Therefore, the 2-3 days before ovulation and 1-2 days after ovulation are the fertile period. This is the stage when ovulation test strips need to be used for monitoring, which usually needs to be used for 5 consecutive days.

2. Don’t use first-morning urine for testing

The best time to test is between 10 am and 8 pm every day, and try to use urine collected at about the same time. The first urine in the morning cannot represent the actual value because of the LH value accumulated overnight, so it is best not to use it. In addition, do not drink too much water within 2 hours before the test to avoid diluting the luteinizing hormone in the urine and affecting the test results.

3. Read the results within the time specified in the instructions.

When using, you should strictly follow the instructions and read the results within the specified time. If the specified time is exceeded, the results will be invalid.

4. What factors will affect the test results?

Commonly used medicines (such as cold medicines, antibiotics, painkillers, etc.) do not affect the accuracy of the test. However, pregnancy, menopause, taking hormones, steroids and contraceptives can affect the test results, so it is best to avoid similar situations or taking similar medications during the test period.

5. Keep the test paper or test pen to compare the results

After completing the test, it is best not to throw away the test paper or test pen immediately. You can keep it for comparison with future tests. Or you can record the test results in detail until the LH peak is detected.
