What Happens After Ovulation And Conception
If a sperm fertilizes an egg, the fertilized egg travels down the fallopian tube to the womb , while the cells continuously divide to form a cluster, called a blastocyst. Around 9 11 days after fertilization, the blastocyst implants into the uterine wall and the embryo begins to develop. After implantation, this is the first time the pregnancy hormone can be detected in the mothers blood or urine.3

When To Take A Blood Pregnancy Test
Maybe youve taken a home pregnancy test, but now your health care provider is suggesting you take a blood test. What exactly is and when should you take a blood pregnancy test?
Home pregnancy tests measure the levels of hCG in your urine. A blood pregnancy test measures the hCG levels in your blood. Health care providers suggest taking a blood test because theyre more sensitive and can offer more information than a home urine test.
The best time to take a blood pregnancy test is if your period is several days late. If your home pregnancy tests are negative, but youre experiencing all the symptoms of pregnancy, its a good idea to take a blood test.
The most accurate blood tests are quantitative blood pregnancy tests, because they determine the exact amount of hCG in your blood. This is important because it can tell your health care provider if youre pregnant or if you need to do another test in a few days.
Health care providers also recommend blood tests if youve experienced an ectopic pregnancy or a miscarriage in the past. This ensures your health care provider will be able to observe your hCG levels more closely in the first weeks of your pregnancy.
For best results, take the pregnancy test in the morning. First-morning urine exhibits the highest concentration of hCG. Taking your pregnancy test sooner than eight days past ovulation might result in a false negative. Blood tests are more sensitive and can offer more information than a home urine test.
How Does Hcg Doubling Affect Pregnancy
Doctors can also perform quantitative serum beta hCG levels via a blood test. Two tests are usually necessary to verify a normal increase, usually 2-3 days apart. The increase in serum hCG can be interactively monitored.
- Below an hCG level of 1,200 mIU/ml, the hCG usually doubles every 48-72 hours, though a rise of 50-60% is still considered normal and determines how early can pregnancy be detected.
- Between 1,200 and 6,000 mIU/ml serum, the hCG usually takes 72-96 hours to double.
- Above 6,000 mIU/ml, the hCG often takes more than four days to double.
Failure to increase normally may indicate that the pregnancy is not developing well, and can be an early sign of a possible miscarriage or an ectopic pregnancy. After a miscarriage, hCG levels fall steadily back to the non-pregnancy range. Also, an ectopic pregnancy may be suspected when hCG levels fail to double, particularly if the hCG level rises, falls and rises again.
When In Doubt Test
Sexually active women in their reproductive years have a chance of pregnancy every month, even when using protection. There are certain signals your body might send that should prompt you to take a pregnancy test.
For the best results, take the test after you think youve missed your period. Test during your first morning bathroom visit, or hold it for several hours to increase the concentration of the HCG hormone that the test measures.
Testing early helps to ensure that you get proper care for yourself and, if applicable, prenatal care for your baby. In the event of a positive result, contact your doctor as soon as possible to discuss your options and potential next steps.

When To Take A Home Pregnancy Test
The length of time from the first day of a period to ovulation can vary by several days from month to month. Sexual activity around ovulation leads to the possibility of fertilization of an released egg by sperm. But even then, the time frame for a fertilized egg to implant can vary. And hCG isnt produced until after implantation has occurred.
For the most accurate results, we recommend testing in the morning on the day you expect your period to start. This allows for variability in the timing of ovulation, fertilization, and implantation. Testing in the morning provides a more concentrated urine sample.
Follow the directions carefully to get the best results. Before you take the test, make sure you understand what the readout for pregnant and not pregnant will be. Some tests still use two lines to indicate you are pregnant and one to indicate that you arent. However, many tests have switched to words such as yes and no, or pregnant and not pregnant for additional clarity.

When To See A Doctor
Most women who have a positive pregnancy test should wait a week or two before calling the Ob/Gyn office for a pregnancy blood test or ultrasound to confirm the pregnancy. We suggest waiting because the rate of early pregnancy loss is high, and its possible that you might have had a chemical pregnancy.
However, women with a history of ectopic pregnancy or current abdominal pain should call the doctor right away to be examined. Ectopic pregnancies implant outside of the uterus and produce hCG, resulting in positive pregnancy tests. However, these pregnancies can cause abdominal bleeding and prompt medical care is necessary. Women who have congenital heart defects or other chronic physical or mental health conditions should also see a doctor right away because treatment plans or medications might need to be altered to protect the woman and the fetus.
Advances in home pregnancy tests give women greater insight into whats going on in their bodies sooner than ever before. No matter what your childbearing plans might be, its essential to get quick, accurate results at home to plan your next steps accordingly.
Youre Not Pregnant: Evaporation Line
Taking a home pregnancy test and getting a faint positive line doesnt always mean youre pregnant. Sometimes, what appears to be a positive line is actually an evaporation line. These misleading lines can appear in the results window as urine evaporates from the stick.
If a faint evaporation line develops on your home pregnancy test, you may mistakenly think that youre pregnant.
It can be hard to determine whether a faint line is a positive result or an evaporation line. The primary difference is that evaporation lines appear in the test window several minutes after the recommended time for checking the test results.
If you take a home pregnancy test, its important to read and carefully follow the instructions. The package will let you know when to check your test results, which can be within three to five minutes, depending on the manufacturer.
If you check your results within the recommended time frame and see a faint positive line, youre most likely pregnant. On the other hand, if you miss the window for checking the results and you dont check the test until 10 minutes later, a faint line may be an evaporation line, which means youre not pregnant.
It also helps to take the home pregnancy test first thing in the morning. The less diluted your urine, the better. Make sure you check the results within the appropriate time frame to avoid confusing an evaporation line with a positive line.

How Is The Hcg Urine Test Performed
You can take an hCG urine test at your doctors office or at home with a home pregnancy test.
Both will require the collection of a urine sample. An hCG urine test conducted at home is similar to the test that your doctor conducts. Both have the same ability to detect hCG in your urine.
Most hCG urine tests sold for home testing follow a similar procedure for accurate testing. While you should carefully follow the instructions included with your kit, the process typically goes like this:
Wait 1 to 2 weeks after your first missed period. We know its hard to be patient! But if you can hold out, youll get the most accurate results. Irregular periods or miscalculations of when a period is due can affect your test.
In fact, 10 to 20 percent of pregnant women may not detect their pregnancy by testing on what they believe to be the first day of their first missed period, according to the Food and Drug Administration . If you can be patient best to wait a few days!
Plan to use the test the first time you urinate after waking up. This urine is the most concentrated and will contain the highest hCG levels of the day. Your urine dilutes as you drink liquids, so hCG levels may be harder to measure later in the day.
For most tests, it only takes about 5 to 10 minutes for a result to appear. Typically, a colored line or plus symbol will appear on the test stick to indicate a positive result. The absence of a colored line or a negative sign usually indicates a negative result.
What About Early Pregnancy Tests

The first thing to consider is that the percentage provided on the front of the package is only accurate when you take the test on the day of your expected period and in a laboratory setting by professionals. The same goes for the the instructions printed inside the pregnancy test kit the claims of accuracy are elevated because they do not reflect real-life testing in real-life situations. The results from a University of New Mexico study reveal the chances you can anticipate getting the right answer from an early home pregnancy test:
- One day past your expected period: 100% of pregnancies detected
- On the day of your expected period: 96% of pregnancies detected
- On the day before your expected period: 93% of pregnancies detected
- Two days before your expected period: 81% of pregnancies detected
- Three days before your expected period: 68% of pregnancies detected

When Should You Take A Pregnancy Test
Before You Miss Your Period
The earlier you take a test, the less accurate it will be. Taking a test before you miss your period or less than two weeks after sex can cause a false negative. Some women take a test too early and assume they are not pregnant. This can be especially confusing if they spot or bleed during their first-trimester, making them believe they had their period.
We see clients who are already entering their second trimester by the time they notice more obvious pregnancy symptoms and are shocked to find out they are pregnant.
Two Weeks Later
Many women test according to the two weeks rule. This can provide accurate results for women who are on a predictable 28-day cycle and who ovulating once and at a regular interval.
However, some womens cycles are not as predictable or medications such as birth control and antibiotics can change their cycle and date of ovulation. Even stress can cause interruptions.
After You Miss Your Period
The best time to take a pregnancy test is the day your period is supposed to start or after you realize your period is late. If your results were still unreadable or inconclusive, take one again the next day. For more accurate results, take a test when you first wake up. The hCG hormone is higher and more concentrated in the morning.
If the test is negative but you still think you may be pregnant, wait a few more days and test again. HCG nearly doubles about every two days in early pregnancy.
