First Symptoms of Pregnancy

Por: Tiago


Generally, when a woman is expecting a baby, within the first few weeks she begins to feel the first symptoms of pregnancy. This is due to the changes both physical and hormonal that will occur throughout this journey.

The first symptoms of pregnancy can be quite evident in some women, while in others they may even go unnoticed. Lucky them! All this because each woman is a “world” and symptoms can vary from one person to another.

But what really are the first symptoms of pregnancy? Check out what signs may indicate pregnancy and what tests can be done to confirm it.

How Do I Know I’m Pregnant? Discover The Main Exams

When a woman is pregnant, the hormone HCG, the famous pregnancy hormone, is secreted. It can be easily detected in blood or urine. See the main tests that can be done to confirm a pregnancy:

Beta HCG Exam

This blood test can detect pregnancy when your period is about 5 days late. It is one of the most efficient and safe methods, as it is extremely sensitive.

Pharmacy Home Test

To take the home test normally found in pharmacies, you do not need to go to a laboratory. Just collect the urine and follow the test instructions. Just like the blood test, this test detects the concentration of HCG. However, the amount found in urine is much smaller, being a less sensitive test. However, it can be quite accurate.

Ultrasonography of the Uterus

Ultrasound is one of the most effective methods for confirming a pregnancy. In addition, it is also used to observe the location of the pregnancy and whether it is topical or ectopic, the baby’s vital signs, measure the embryo, among others.

You can also take an online pregnancy test if you don’t feel ready to see a doctor yet. By answering a simple questionnaire you will be able to quickly find out your chances of being pregnant.
