The pregnancy test can be done from 1 week before the scheduled date for the next menstruation . For example, if menstruation should start on the 10th, starting on the 3rd of that month, a pregnancy can already be detected by tests (mainly blood tests).
Even so, in order for a pregnancy test to be more effective, it is advisable to wait for menstruation to be delayed before doing it.
How many days can I take the pregnancy test?
There are 2 types of pregnancy tests that are proven to work: the pregnancy test done by laboratory blood test and the pharmacy pregnancy test.
Both tests measure the presence of the hormone Beta hCG, which is only released in the female body when the woman is pregnant.
Fertilization can take up to 6 days to occur and the zygote (egg fertilized by sperm) needs, on average, 1 week to stay in the uterus.
So, if there is a chance of pregnancy, do the first pregnancy test about 2 weeks after the possible conception.
It is recommended that the blood pregnancy test be performed only after a minimum of 2 days delay of menstruation. If the menstrual cycle is irregular, you should wait more days to see if menstruation will come or not.
Taking the exam before that time can generate a “false negative” as a result.
In some cases, women younger than 3 weeks may have a negative pregnancy result, as they may release low amounts of the hCG hormone early on that will not be diagnosed on the blood test.
The blood pregnancy test is a common laboratory test and takes a few minutes to complete. You should wait about 3 days if you want to repeat the exam.
The pharmacy pregnancy test should be done only after menstruation is delayed. 2 days of menstrual delay may be enough for the exam to detect pregnancy. It is important to note that even if the pharmacy test indicates “negative”, there are still chances of pregnancy.
This is because these pharmacy tests measure the amount of hormones (mainly Beta HCG) present in the woman’s body only during pregnancy.
If these substances are being produced, but in low quantities, the pharmacy test may indicate “negative”. So, even with this result, if you still suspect pregnancy, look for a gynecologist.
If the pregnancy test is done too early or in the wrong way, it also has a high chance of indicating ‘negative’ even if the woman is pregnant.
If done on the right day and in the proper way, pharmacy pregnancy tests have, on average, a 95% chance of being accurate in the result.
When should I take the pregnancy test if the menstrual cycle is irregular?
If the menstrual cycle is not regulated, wait at least 15 days behind a normal cycle (28 days). That is, count at least 43 days after your last period.
Unregulated cycles do not prevent pregnancy, they only hinder discovery. So if you experience symptoms and suspect pregnancy, get tested.
When to do the pregnancy test after undergoing IVF ?
It depends on the case. There are two possibilities:
- Fresh embryo transfer: in this case, the woman must take the pregnancy test 14 days after fertilization;
- Transfer of the thawed embryo: in this case, the woman must take the pregnancy test between 9 and 11 days after fertilization.
If you have undergone an in vitro fertilization and do the test before the correct day, the result may be “false positive”.
That’s because the amount of Beta hCG hormone (applied at the end of the procedure) can still be present in the body and be detected by pregnancy tests.
What are the symptoms of pregnancy?
The main symptoms of pregnancy are:
- Sensitive and sore breasts;
- Sickness and dizziness;
- Mood swings;
- Fainting and loss of consciousness.
These symptoms alone are not enough to confirm a pregnancy, as they may be related to other conditions and diseases.
It is also possible that some women are pregnant and do not experience any of these symptoms.
Therefore, in case of suspicion, the most recommended is to consult a specialist for the correct diagnosis.
Given the symptoms of pregnancy, the hypothesis of a pregnancy is always considered. Pregnancy tests prove pregnancy or not. The positive result foreshadows motherhood and promises great changes in life.
