Do the pregnancy test to be reliable, when and how? urine or blood? morning or afternoon? get out of doubt
In this post, we tell you when you should take the pregnancy test so that the result is reliable, whether it is positive or negative.
First of all, I want to tell you exactly what the home pregnancy test evaluates so that you understand the importance of performing the pregnancy test at that specific time.
La pregnancy hormone begins to be produced after the contact of the embryo with the wall of the mother's uterus, the endometrium. This contact produces the hormone called beta hcg that only women produce when we are pregnant.
This pregnancy hormone will increase its level in the body at a rate of doubling every 48 hours, so if we do not do the pregnancy test at the correct time of the cycle or day, we can have a negative and two days later it is positive.
To clarify one thing, if we do the pregnancy test just after conception, it will not be able to give us a positive because it is still too early, we have to wait a few days, even if it is to do the test before waiting for the menstruation or to adapt the pregnancy test at ultraearly or in blood. At the end of the post I give you a summary table with everything you have to take into account before buying your test. I tell you….
What time of the cycle to do the pregnancy test
Thus, the closer we get to the time of the rule or menstruation, the higher the level of the human chorionic gonadotropin hormone will be and therefore the easier it will be to detect that positive.
However, if you are pregnant and do the early detection type test, you can even know if there is a pregnancy 6 days before the missed period. If 6 days before your period is negative, don't get overwhelmed, it may be too soon and it's better to wait a couple of days to repeat the pregnancy test.
If you are already waiting for your period and it does not arrive or you are late, you can now take the test without waiting any longer.
In summary;
- Test before period: It must be highly sensitive. Like this LINK
- Test when there is already a fault: it can be a generic test like this LINK
At what time of day to do the pregnancy test? When to do the test?
The pregnancy hormone will be found in the blood and from this it will pass into the urine. If we haven't urinated for hours, the hcg hormone will be in higher concentration than if I'm at another time of day or we've just had a lot to drink.
So, if you are still waiting for your period and you have recently conceived, it is better to do the test with the first urine of the day. In this way, if there is hcg hormone, it is more likely that the pregnancy test will detect it.
If you are already late, you can take the pregnancy test at any time of the day, that is, when to take the pregnancy test would not be an important factor in your case.
In short, what time of day to do the test if:
- If you still do not have any delay: then it is better to do the test with the first urine of the day to have a reliable result. If it has been negative, repeat the test the next morning.
- If you are already a day late: You can take the test any time of the day. In this case the presence of the hormone is greater. Also, if you are pregnant you can have the test that tells you how many weeks you are that detects it and defines it based on the levels of the pregnancy hormone.
what kind of pregnancy test
To be able to detect pregnancy from home we have homemade pregnancy checks. These can be done from home since they are easy to use and interpret and in 5 minutes at most we already know if there is a pregnancy or not.
These pregnancy tests are normally performed on urine, but recently we can also test blood from home. Before, blood tests were reserved for clinics and hospitals and thanks to technology we now also have blood pregnancy tests to do from home.
In short, you can analyze if you are pregnant from home with these types of pregnancy test:
- In blood: if you want to know very soon and at any time of the day. In this case, since it is in the blood, you do not have to wait until it is morning and have concentrated urine. You can do it from long before there is a delay and shortly after conception. I leave here the link to ultra-early pregnancy tests at home. LINK
- In urine: as we have said in this case there are many types and sensitivities. Before buying the pregnancy test, stop to think about when you are going to want to do it, if you are already late or not and also if you are going to need several. So you add them to the cart with a sense and have a reliable result. I'll give you a list of the types there are so you know how and when to do it.
- Ultra early in urine: 6 days before the expected date of the period (LINK)
- Normal: with a missed or late period, it can be in strips (LINK) o digital (LINK)
- Digital: from the fault it already tells you the weeks measuring the amount of hormone in your urine (LINK)
Before you buy the pregnancy test
Remember, ask yourself How many pregnancy tests do I need? There are women who also prefer to have several to be able to carry out the test for several days and if there is a positive result, they also continue to carry out the pregnancy tests to have proof that it is there until they can be 6 or more weeks old and be able to do an ultrasound.
Do you want to read about false negatives and possible false positives? Well, you can read this other post in which I tell you when and how this can happen. strange situation of having false results.
Apart from the tests, keep in mind that a good way to know where we are is to notice the symptoms and changes in health. In this other post I talk to you about the differences between pregnancy and premenstrual syndrome so that you can know the changes that are normal and those that are related to the positive.
