If you think you may be, take a pregnancy test immediately after the first day of your period can help you get the care and support you need. A home pregnancy test can tell whether you are pregnant with an accuracy of nearly 99%, depending on how you use it. If the pregnancy test says you are pregnant, you should see your doctor for other tests to confirm the pregnancy and talk about next steps.

Some home pregnancy tests are more sensitive than others and can be taken before your missed period. But you may get more accurate results if you wait until after the first day of your menses.

This is because the amount of pregnancy hormone, called human chorionic gonadotropin, or hCG, in your urine increases with time. Before you take the test, the more difficult for the test to detect hCG.

hCG is created when a fertilized egg implants in the uterus. This usually occurs about 10 days after conception (when the sperm fertilizes the female egg).

If the home pregnancy test shows that you are pregnant, you should call your doctor to schedule an appointment.

Your doctor can use a blood test to ascertain whether you are pregnant. Seeing your doctor early in your pregnancy also means you can begin to help you and your baby stay healthy.

Yes, it is possible you could still become pregnant. , It's possible to get pregnant and have the show pregnancy test that you are not pregnant

The accuracy of the results of a home pregnancy test varies from woman to woman because:

If the test says you are not pregnant, take a pregnancy test the other in a few days. If you are pregnant, your hCG levels should double every 48 hours. If you think you are pregnant, but more tests say you do not, call your doctor.

Sometimes it can be difficult to tell if the test is positive or negative. This path may be faint, or you may worry whether you urinate too much or too little on sticks.

No matter how faint lines or the plus sign, if you see it, you are most likely pregnant. The faint lines can mean you are early in your pregnancy and your hCG levels are still low.

In addition, a pregnancy test must have a control line that tells you whether the test is performed correctly. If the control line is blank, the test does not work and you have to take another test

Pregnancy tests check the hormone hCG in two ways :.

All home pregnancy tests come with written instructions. Depending on the brand you buy, the instructions may be different:

different brands tell you to wait for a different time, though mostly about 2 minutes. Depending on the brand of the test, you might see a line or plus symbol, or the word "pregnant" or "not pregnant." A line or plus symbol, no matter how faint, means the result is positive.

Most tests also have a "control indicator" in the results window. control line or symbol shows whether the test is working properly. If the control line or symbol does not appear, the test is not working properly.

Look for a toll-free telephone number on the package to call in case of questions regarding the use or the results.

Most of the home pregnancy test claimed up to 99% accurate. But the accuracy depends on:

Most pregnancy tests claim to be the most accurate after a missed period. But irregular periods can make it difficult to predict when to take a test

The period is considered irregular if :.

If you have irregular periods, try counting 36 days from the start of your progress or four weeks from the time you have sex. At this point, if you are pregnant, your levels of hCG should be high enough to detect pregnancy.

If your test says you are not pregnant, but you still think you might be pregnant, wait a few more days and take another pregnancy test. Or, call your doctor for a blood test.

Yes. If you take the medicine with the pregnancy hormone hCG as an active ingredient, you may get a false positive test results. A false positive is when the test says you are pregnant when you do not.

Some examples of medicines with hCG include certain drugs for infertility. If you are taking medication to help you get pregnant, you may want to see your doctor for a pregnancy test.

Most medications should not affect the results of a home pregnancy test. This includes over-the-counter and prescription drugs such as birth control and antibiotics. Also, alcohol and drugs do not affect the results of a pregnancy test.

All pregnancy tests work by detecting the pregnancy hormone, hCG, in your urine or blood. This hormone is present only when a woman is pregnant. If the pregnancy test detects hCG, he would say you are pregnant.

hCG is created when a fertilized egg implants in the uterus. This usually occurs about 10 days after conception (when the sperm fertilizes the female egg). Total hCG rapidly accumulate in your body every day you are pregnant.

So, if you take a home pregnancy test too soon after implantation, your hCG levels may not be high enough to detect pregnancy. If the test says you are not pregnant, take another pregnancy test within a few days
