What Is The Most Accurate Pregnancy Test
In the largest study of over-the-counter pregnancy tests to date, First Response proved to be 97 percent accurate from the day of your missed period for both its digital and manual line tests.
However, the study was conducted in 2011 and only compared six over-the-counter tests from three major brands. Many brands may have changed their technology since. Newer direct-to-consumer brands that have burst onto the scene, as well as other brands not included in the study, may prove to be just as accurate.
Can You Confirm Pregnancy From Changes In The Sleep Pattern
A pregnant womans sleep pattern changes owing to the increased levels of progesterone in her body. However, a woman might lose sleep due to a host of other reasons, so it is wrong to conclude that someone is pregnant just because she is not sleeping well.
A combination of the above-mentioned signs can indicate that you are pregnant if only one or two affect you, you are most likely not pregnant. However, do pay the doctor a visit to confirm that you are going to have a baby if you experience some of these symptoms.
How Do Homemade Pregnancy Tests Work
Homemade pregnancy tests work the same way as any over-the-counter pregnancy test by detecting the hormone human chorionic gonadotropin . If you test positive, you may observe a chemical reaction between hCG in your urine and the substance you are using to test.
Your cells start to produce the hCG hormone when they start creating the placenta. This hormone increases rapidly early in pregnancy and enters your bloodstream and urine, confirming conception .

The most accurate time to test is starting on the day of your missed period and the week after.

Will You Notice Early Signs And Symptoms When You’re 1 Week Pregnant Or 2 Weeks Pregnant
Your journey through pregnancy has officially begun, but as mentioned above, youâre not actually pregnant yet. Remember that healthcare providers calculate your pregnancy as 40 weeks, or 280 days, from the start of your last period. So, if you have a typical 28-day menstrual cycle, the first two weeks are mainly just Aunt Flo doing her thing.
But after two weeks, other things start to happen.
One of your ovaries will release an egg around 14 days after the first day of your last period.
The egg will travel down one of the fallopian tubes where it may unite with sperm.
Itâs worth noting that sperm can live inside your body for up to five days, and your egg has a lifespan of up to one day. This means your window of fertility is about five days before you ovulate to one day after.What this all means is that you wonât feel any of those very early signs of pregnancy in weeks 1, 2, or possibly even 3. If you have yet to conceive, then it makes sense that you wouldnât notice anything!

Home Pregnancy Test Preparation
To get the best results from your home test kit, follow the instructions that come with the kit.
Read the label and instructions carefully: Review all instructions and pictures to make sure you understand how to perform the test. The instructions will tell you the following information:
- Why the pregnancy test is used
- How to collect and store your urine sample
- When and how to run the test, including timing instructions
- How to interpret the test results
- What might interfere with the test results
- The manufacturer’s phone number if you have questions
- Only use tests regulated by FDA: Ask the pharmacist how you can know if a home use test is regulated by the FDA. If a test is FDA approved, the US government has not determined the product to be reasonably safe or reliable.
- Follow all instructions: You must follow all test instructions to get an accurate result. Most home tests require specific timing, materials, and sample amounts. You should also check the expiration dates and storage conditions before performing a test to make sure the components still work correctly.
- Keep good records of your testing.
- When in doubt, contact your doctor: All tests can give false results . You should see your doctor if you believe your test results are wrong or to confirm the result.
Don’t change medications or their dosages based on a home test without talking to your doctor.
How Do Home Pregnancy Tests Work
Home pregnancy tests detect a hormone in your urine called hCG . When a sperm and an egg join and start growing, some of the cells start producing hCG.
Levels of hCG rise rapidly in early pregnancy, and this is what home pregnancy tests are checking for.
At-home pregnancy tests usually work one of two ways: You either hold the stick in your stream of urine , or you pee in a cup and dip the stick in.
You then lay the stick or strip flat and wait the amount of time given on the box .
For the most accurate results, its best to wait at least until after your period was due to start. Before this, there just might not be enough hCG in your urine to be detected on a pregnancy test.
If you get a negative result on your pregnancy test, it might just be too early to tell. Try waiting a few days, then check again. Its more common to get a false negative on a pregnancy test , but false positives do occasionally happen.

False Negative And False Positive Pregnancy Tests
Unfortunately, sometimes pregnancy test results arent accurate. Its possible to get a result that says youre not pregnant when you are or that youre pregnant when you arent .
You may have a false negative result if you take a pregnancy test too early, the test is defective, or you have problems with the pregnancy.
A false positive result can happen if the pregnancy test doesnt work correctly or detects HCG in your urine or blood for another reason. For example, HCG may show up if you take the test shortly after taking fertility drugs that contain HCG, such as Pregnyl or Profasi.
All in all, the most common reason for a misleading pregnancy test is taking it too early before your HCG levels have risen.
When You Can Do A Pregnancy Test
You can carry out most pregnancy tests from the first day of a missed period. If you don’t know when your next period is due, do the test at least 21 days after you last had unprotected sex.
Some very sensitive pregnancy tests can be used even before you miss a period, from as early as 8 days after conception.
You can do a pregnancy test on a sample of urine collected at any time of the day. It doesn’t have to be in the morning.

How Early Can Home Pregnancy Tests Show Positive Results
In the Aerosmith song Sweet Emotion, Steven Tylers lyric the rabbit done died refers to the original way a pregnancy test was performed one that literally killed rabbits. Urine from a woman who thought she might be pregnant was injected into a rabbit, which would then be surgically opened so its ovaries could be inspected. If the woman was pregnant, the rabbits ovaries would undergo noticeable changes due to the hormone human chorionic gonadotropin that develops early in gestation. The rabbit unfortunately didnt survive.

Early Signs You’re Pregnant Before A Missed Period
Early pregnancy symptoms can overlap with common body changes, such as PMS. Here’s how to tell the difference.
Your menstrual cycle is your body’s monthly preparation for pregnancy — if you get pregnant, the lining in your uterus has a job to do and you won’t experience any typical menstrual bleeding. But while a missed period is many people’s first signal that they’re pregnant, it often isn’t the first clue your body gives you.
In the first weeks of pregnancy , the body starts producing a lot of hormones that can affect you physically and mentally. In addition to amping up its regular production of progesterone and estrogen, your body starts producing new ones, including human placental lactogen and human chorionic gonadotropin .
While your body is in hormonal overdrive during early pregnancy, you may feel some side effects. But if hormones are to blame, how do you tell if it’s PMS, ovulation symptoms or something else completely? Below, we outline some signals you might notice from your body during early pregnancy, before you even take a pregnancy test.

- Make sure to collect a substantial amount of urine. If it is too low, you may end up with incorrect test results.
