When to Take a Pregnancy Test
A pregnancy test is a device used to detect the presence of human chorionic gonadotropin (hCG) in urine or blood. hCG is a hormone produced by the placenta after implantation of a fertilized egg. The amount of hCG in the body increases rapidly during the early stages of pregnancy.
When to Take a Pregnancy Test
The best time to take a pregnancy test is after you have missed your period. However, some tests can detect pregnancy as early as 10 days after ovulation. If you are unsure when you ovulated, you can take a pregnancy test 14 days after unprotected sex.
Types of Pregnancy Tests
There are two main types of pregnancy tests: urine tests and blood tests.
- Urine tests are the most common type of pregnancy test. They are available over-the-counter at pharmacies and grocery stores. Urine tests can be used to detect pregnancy as early as 10 days after ovulation.
- Blood tests are more accurate than urine tests. They can be used to detect pregnancy as early as 6 days after ovulation. Blood tests are typically performed in a doctor’s office or laboratory.
How to Take a Pregnancy Test
To take a pregnancy test, follow these steps:
- Read the instructions carefully. Each pregnancy test is different, so it is important to read the instructions carefully before using it.
- Collect a urine sample. If you are using a urine test, collect a urine sample in a clean container.
- Apply the urine to the test strip. Dip the test strip into the urine sample for the amount of time specified in the instructions.
- Wait for the results. The results of the pregnancy test will appear within a few minutes.
Interpreting the Results
A positive pregnancy test result means that you are pregnant. A negative pregnancy test result means that you are not pregnant.
If you get a positive pregnancy test result, you should make an appointment with your doctor to confirm the pregnancy and discuss your options.
If you get a negative pregnancy test result, but you still think you might be pregnant, you should wait a few days and take another test.
Factors That Can Affect the Accuracy of Pregnancy Tests
There are a number of factors that can affect the accuracy of pregnancy tests, including:
- The time of day you take the test. Pregnancy tests are most accurate when taken first thing in the morning.
- The amount of urine you use. If you use too little urine, the test may not be able to detect hCG.
- The type of pregnancy test you use. Some pregnancy tests are more sensitive than others.
- Your health. Certain medical conditions, such as kidney disease, can affect the accuracy of pregnancy tests.
If you have any questions about pregnancy tests, talk to your doctor.
