Your period has stopped – are you perhaps pregnant? A pregmate pregnancy test is the best way to find out. You can find out exactly how it works and by which physical changes you can also tell if you are pregnant here.
A pregnancy test is useful if the following physical changes indicate a pregnancy:
- Absence of menstruation
- Feeling of tension in the breast, enlarged and firmer breasts
- Darker and firmer labia due to the stronger blood circulation
- Morning nausea, appetite disorders, exhaustion and tiredness
- Skin changes: an increased tendency to pimples (with impure skin) or dry and sensitive skin
- Stronger outflow
- Sustained elevated body temperature
How a pregnancy test works
A pregnancy test is based on the detection of the pregnancy hormone beta-HCG (= beta-human choriogonadotropin) in blood or urine. The hormone causes the further release of estrogens and progestins from the corpus luteum in the ovary.
If there is no pregnancy, the corpus luteum recedes and the uterine lining is broken down: Menstruation begins.
In the case of an existing pregnancy, hormone detection is successful as early as six to eight days after fertilization. This means that about two days have elapsed since the egg has been implanted in the uterus.
In pregnancy tests, a distinction is made between urine and blood tests. Today, urine tests are already so sensitive that the pregnancy hormone can be detected in the morning urine shortly before the expected period. In principle, however, a positive reliable test result can only be expected on the second day after the absence of the period. HCG is detected in the blood earlier than in the urine. These tests normally provide a reliable result two days before the period.
First read, then test
Urine tests carried out at home can, therefore, provide relatively reliable results as early as the second day after the absence of the period. The package insert shows the procedure step by step and must therefore always be read carefully. Pregnancy tests are available in all pharmacies and drugstores. The reliability is stated to be 90 to 98 percent, although this increases with the age of early pregnancy.
Unclear test results
Possible reasons for an incorrect test result are inaccurate handling, old or incorrectly stored tests and the use of certain drugs (hormone preparations, antidepressants, and others).
The result is negative, but the woman is still pregnant: in this case, the test may have been carried out too early, so that there was not yet a sufficiently high level of HCG in the urine to detect it.
The test is positive, but there is no (further) pregnancy: It happens relatively often that fertilization and also the implantation of an egg takes place, but in the first few days there is an abnormal development of the ovary. The woman usually does not notice the pregnancy, sometimes only the menstrual bleeding is postponed.
This can be very depressing for women with a pronounced desire to have children. In these cases, pregnancy tests should therefore only be carried out after the menstrual bleeding has stopped (possibly even later).
Reliable pregnancy signs are determined by the doctor:
- Urine and blood test positive
- Ultrasound image of the child: Only six weeks after the last period, and amniotic sac is visible, one week later the embryo and after another week already his heartbeat
- Fetal heart tones
- Movements of the child
