Can I use an early pregnancy test strip to detect pregnancy on day 5?

According to gynecologists, pregnancy can be detected 18 days after intercourse or when the menstrual cycle is delayed by less than 7-10 days. This is because after the sperm and egg combine to form a sperm-egg combination, the embryo implants in the uterine wall 6-8 days later, and the HCG secreted by the embryo enters the urine 7-10 days later. The sum of the two is the scientific method to test whether the pregnancy is confirmed by urine 18 days after intercourse. Pregnancy can be detected within the first seven days, usually around fourteen days, and rarely more than twenty days after sexual intercourse.

Clinically, the first day of the expected delivery period is used as the starting point for calculating the time of pregnancy. Every 7 days is a pregnancy week, and every 4 days is a pregnancy month. For women with regular menstrual cycles, it is recommended to test at least 7 days after the menstrual period to confirm pregnancy. If you can't remember the due date of pregnancy, you can use B-ultrasound to determine the time of pregnancy.

The advent of early pregnancy test strips has brought great convenience to the diagnosis of early pregnancy. On the seventh day of a woman's pregnancy, a specific growth hormone, human chorionic gonadotropin (commonly known as HCG), can be detected in her urine, which is beneficial to maintaining pregnancy. Under normal circumstances, put urine into the inspection hole on the test paper. If a colored band appears in the comparison area of ​​the test paper (some test papers appear red, some test papers appear blue), it indicates that you are not pregnant.

On the contrary, if a significant printed color band appears in the test area, the displayed information is positive, indicating pregnancy. This type of test has the advantages of being rapid, convenient, flexible, and highly specific, and can avoid reactions caused by other glycoprotein hormones with a similar structure to HCG.

How to use early pregnancy test paper

1. Use a disposable urine cup or clean container to collect urine.

2. Tear off the aluminum foil bag along the wound position and remove the test paper for inspection.

3. Strip form: Place the end of the test paper with the arrow mark into the container containing the urine sample to be tested (the urine sample is not allowed to exceed the MAX line), and remove it after about 3 seconds. (As shown below)

Three-in-one: Use a plastic pipette to draw 0.2mL (3-4 drops) of urine sample to be tested into the sample addition area.

Pen type: Remove the cap and let the urine immediately drip onto the sample area while urinating, and keep the urine collection time for about 3 seconds (Note: the urine does not need to exceed the arrow symbol to prevent the urine from wetting the test area and affecting the test results).

4. Observe the test results in the testing area: Observe the test results within 5-10 minutes. Coloring within 40 seconds is strongly positive.

Positive: Printed color bands appear above and below the test strip, indicating pregnancy.

Negative: Only a dark purple band appears above the test strip and no color band appears below, indicating no pregnancy.

Failed: No color band appears. Indicates that the test strip is invalid.
