Home rapid pregnancy tests are no longer a gimmick. They are firmly embedded in the life of a modern woman. And yet, the ladies have many questions about their application. Many are interested in the issues of reliability and early diagnosis of pregnancy using tests. Every woman knows that it is possible to do a pregnancy test before a delay in menstruation - you definitely will not harm your health. But whether the results will be true, and are there such tests in nature that are able to determine conception immediately after fertilization. Let's discuss this important topic.

Test before delay

How a pregnancy test works

Until 30 years ago, home pregnancy tests were not so popular. All examinations, analyzes, diagnostics were carried out mainly by doctors in antenatal clinics.

Progress has stepped so far that it is possible to find out about the presence of a fetus at the earliest possible date. There are certain periods before the delay when a pregnancy test can be done, within the limits due to the sensitivity of the devices themselves.

Usually, modern tests for diagnosing pregnancy at home give true results. With their help, pregnancy is determined even before the onset of the control moment.

All diagnostics, both at home and in a medical institution, are based on the recognition of the chorionic gonadotropin hormone by reagents with antibodies. In the blood of a pregnant woman, hCG begins to be produced from the moment the fetus is introduced into the endometrium. The concentration of hormones approaches the level recognized by the reagents in the form of a second strip approximately 8-10 days after conception.

The first indicators in the blood are 5 days ahead of the analogous hCG indices in the urine. This means that an analysis for determining pregnancy at home according to urine indicators can be done somewhere 13-14 days after fertilization.
This period usually corresponds to the onset of the onset of menstruation, and falls on 4-5 weeks of pregnancy.

Important! Of no small importance in determining conception is the sensitivity of the device used. The most sensitive of the variety of instrument types are digital testers. On the packaging box, the manufacturer must indicate the numbers regarding the sensitivity of the test: 10, 15, 20, 25 IU. Choose the test with the lowest scores. The lower the numerical value of the tester, the more sensitive and accurate it is.

When is the best time to do testing

It would seem that everything is clear: the manufacturers of the most sensitive tests promise their customers two strips already 7 days after the formation of the ovum. But not everything is so simple, some may succeed, but some will not. Not all women have the same amount of hCG in their bodies at the same gestational age. The content of pregnancy hormone in urine differs for a variety of reasons.

  1. The duration of the female cycle.
  2. The date on which you ovulate.
  3. When fertilization took place.

Important! A positive result may appear when the pregnancy really was, began to develop, and then suddenly it was interrupted. Most gynecologists believe that the minimum period when conception can be determined using a home express pregnancy test is 2 days before menstruation.

Will the test show fertilization before the delay?

A reliable result before a delay in menstruation is possible, and there are many examples of this.
For the result to be reliable, you still need to follow certain rules.

  1. For early diagnosis, a tester with a maximum sensitivity of 10 IU should be used. This means that the tester is able to determine the presence of hCG hormones at a concentration of 10 units. one milliliter.
  2. The manufacturer, for the sake of advertising, can write that diagnostics can be carried out at any time, but you are not fooled by this. Do your study using morning urine: this is where the highest amount of hormones not diluted overnight is there, since you did not eat or drink anything.
  3. With early diagnosis, there may be errors, so check the indications of the first study in the next 2-3 days.

5-6 days after conception

At this stage in the development of medicine and gynecology, it is unlikely that it will be possible to learn about the beginning of a new life 5-6 days after conception. Since the hCG hormone, which all tests are guided by, is released only after the embryo has attached itself to the lining of the uterus and begins to receive nutrition from the blood vessels of its mother. And this exciting process takes place no earlier than 5 days after the formation of the zygote. And most often on the 7th day, or even on the 10th. With a cycle of 30 days - on the twenty-seventh or thirtieth day, with a cycle of 25 days - on the twenty-fourth day, and with a cycle of 26 days - on the twenty-third or twenty-sixth day.

That is, while all testing is based on the detection of gonadotropin, it is not worth looking for it in the blood and urine of a woman before it appears and catching the second strip is not worth it.

7-8 days after conception

A week after fertilization, the concentration of the hormone in the urine is low. During this period, hCG has just begun to be produced, and is unlikely to manifest itself.

The level of gonadotropin (this hormone is found not only in women, but also in men), initially some people may have 0 units, while others have 5 units all the time.

But a week after the conception of the child, only 2 IU of the pregnancy hormone will be added. And even if in your body, before fertilization, it already contained 5 units, then modern tests are able to recognize at least 10 units. And not in the body in general, but in the urine.

9-10 days after conception

During this period, gonadotropin is already intensively produced by the corpus luteum. By the tenth day, the level of hCG in the body rises to 8 IU. In this case, if the concentration of hormones was initially above zero, then it is quite possible to detect the origin of life at the shortest period.

11-12 days after conception

It would seem that after 11-12 days, tests should accurately determine pregnancy. Everything is possible, but it is absolutely impossible to say that yes, on the 12th day after conception, you will definitely see 2 strips - it is impossible.

It all depends on the individual characteristics of the female body, the day after ovulation, which can be early or late, how long the zygote traveled through the fallopian tube to the place of its "dislocation".

Important! Using testers for at-home conception determination before the delay begins, double-check these results. They are not always straightforward and may be wrong.

Reliability of the result

The most active discussion on women's forums in relation to various testers concerns whether the test will show pregnancy before the delay, and on what day after conception it can happen.

Most gynecologists claim that a home test can determine the presence of an embryo two to three days before the delay, provided that a highly sensitive device is used. From the moment of unprotected intercourse, about 9-13 days should pass, which coincides with the first day of the delay.

To determine the moment of fertilization and implantation of the fetus, you can measure the basal temperature, and then control the process with the help of home diagnostics.

Which testers are the most reliable

A reliable result depends on a certain level of hormones in the body - this is the main condition, but the tester itself is of no small importance in obtaining the correct result. After all, if the reagent is expired, defective or has a weak susceptibility to the detection of the hormone, then even a whole swarm of HCG is unlikely to help you.

The pharmaceutical industry is constantly evolving and produces highly accurate testers that give correct and accurate results. There are 4 types of such devices on the pharmacy market:

  1. Strip tests remain the most popular drugs among women due to their ease of use, accuracy and low cost. The most popular of them are strips of the German brands Evitest and Frautest. Manufacturers achieve high sensitivity due to the use of very high quality reagents in their production. Manufacturers claim that strip strips show quick results before the menstrual cycle is delayed, how many days they do not indicate, but ideally, the test will reliably show pregnancy a couple of days after delays.
  2. Inkjet models are convenient in that it is not at all necessary for them to prepare a sterile container. Simply place the plate under the stream of urine. Inkjet machines are more sensitive and are expected to indicate an onset pregnancy one week before the expected delay.
  3. Tablet models have two holes, into one of which you need to drop 4 drops of urine and get the result in 1-10 minutes (why such a difference in waiting is not clear). Not a very convenient option, but since it exists, it means it is in demand.
  4. The most modern, accurate and sensitive are digital models. In this case, pregnancy diagnosis turns into an exciting game with a gadget. The tip of the device is lowered into urine and after exactly three minutes you will be given the result. What is good about this device is that you do not need to look closely: a bright strip or not. The electronic tester, depending on the model, will simply write "+" (positive / pregnant) or "-" (negative / not pregnant). But that's not all. This miracle of technology will tell you the number of weeks of obstetric due date and calculate when your baby is due. In today's pharmaceutical market, it is the most accurate device that can detect pregnancy a week before a delay. The only negative is the price.

Important! The most accurate pregnancy tests that can give results in advance are inkjet and electronic devices.

Before we analyze the most popular pregnancy tests that determine the result before the delay in menstruation, based on the feedback from women, we note one important thing. The best tester is ourselves. Many expectant mothers know about pregnancy in advance. By the beginning of the delay, they no longer need a tester: changes begin in their body, which are signals characteristic of an "interesting position."

  1. Delay of menstruation for more than a week.
  2. Pulling pains in the lower abdomen, radiating to the lower back.
  3. Soreness of the mammary glands and a feeling of fullness.
  4. Constant urge to go to the toilet due to constant frequent urination.
  5. Toxicosis with its eternal nausea and even vomiting.
  6. And against all this background - an unstable psycho-emotional background.

Gynecologists have their own professional methods for determining pregnancy. Specialists are guided by the bluish tint of the walls of the vagina, measure the size of the uterus, see how closed the cervix is, prescribe a blood test for hCG to the expectant mother.

And yet, let's decide which pregnancy test will give the earliest result before the delay. What do young mothers think about this, who have already gone this way from conception to expectation. Let's turn to their opinion.

  1. Many girls, according to the results of a poll in the Internet space, voted for the Clear Blue electronic gadget. A convenient, functional mini-device, with the ability to determine the presence of an embryo 5 days before the expected female days.
  2. Some people preferred the newest test cassette from Farmasco, under the Sizam trademark. The device is ultrasensitive and detects the presence of an embryo seven days after cell fusion and zygote formation. The test time is only 3 minutes.
  3. The same manufacturer also produces an Ultra Strip Strip under the same brand. The device is also in high demand due to its accurate early results.
  4. The French controller from the Inotech firm, under the BB test brand, has very good reviews. Women who used it leave their feedback about it as an accurate tester with reliable results.

But we cannot say that everyone without exception agrees with the indications of home tests. There is also a large percentage of dissatisfied.

Important! Statistics claim that the testing carried out the day before the delay is 98% reliable, and 4 days before - by 65%.

The most reliable way to determine pregnancy

And yet, the surest way to find out about fertilization and take a pregnancy test without delay is to go to a clinical laboratory and donate blood for analysis. This method will detect the presence of an embryo 6-10 days after fertilization of the egg. The analysis is taken in the morning on an empty stomach. The only drawback of this method is its high cost. If in doubt, after a couple of days, testing must be done again.

A photo is attached below for reference - this is a table with the level of hCG in the blood by week.

Home methods of determining pregnancy are not taken seriously now. But if you want, why not try it. You can use a baking soda pregnancy test, run it before the delay, and then check it also with a tester from the pharmacy.

  1. The principle of operation of this study is based on the statement that the acidity of urine is lowered in pregnant women.
  2. Soda (sodium bicarbonate), which belongs to the class of alkaline substances, enters into a chemical reaction with the acidic environment of urine, neutralizing acidity. The urine foams, hisses and bubbles beautifully.
  3. But in pregnant women, the acidity is lowered and the effect of festive champagne does not work.

Advice! Anyway, take urine for such a home study in the morning, not in the evening, and not in the middle of the day.

To summarize the information: 2-3 days before the possible onset of menstruation, you can test, get real, reliable results, and detect pregnancy. But the tester must be ultrasensitive, the study must be carried out according to all the requirements of the instructions and one more important condition: a stable, regular cycle. And then, you can safely prepare for the birth of a little man.
