Exciting changes await you in the first trimester of your pregnancy. In the first few weeks, your body will be preparing for your baby. You may experience morning sickness, and your breasts may become more tender. It's important to maintain a balanced diet and get plenty of rest. Don't forget to visit your obstetrician regularly to make sure everything is going well. This trimester marks the beginning of an exciting journey to motherhood. We'll explain what happens during this exciting time!
Counting the weeks of pregnancy
How are the weeks of pregnancy counted? Your pregnancy lasts 40 weeks. The start of your pregnancy is considered to be the time of your last menstrual period. However, ovulation and fertilization usually occur two weeks later. Therefore, you weren't actually pregnant for the first two weeks of the count. The division of pregnancy weeks into the three trimesters is a rough guideline. In the blog articles on the 1st trimester, 2nd trimester, and 3rd trimester, we use the most common division.
First trimester: 0-12 weeks
Second trimester: 13-27 weeks
Third trimester: 28-40 weeks
The development of the baby in the 1st trimester of pregnancy
The first trimester of pregnancy is an exciting time, during which the tiny fertilized egg develops into a complex embryo. During the first three months, the baby undergoes amazing changes. Let's take a detailed look at your baby's development during this crucial period.
Month 1: implantation and first cell divisions
The development of the baby in the 1st trimester of pregnancy
The first trimester of pregnancy is an exciting time, during which the tiny fertilized egg develops into a complex embryo. During the first three months, the baby undergoes amazing changes. Let's take a detailed look at your baby's development during this crucial period.
Month 2: Organ development begins
The second month also counts as the first trimester of pregnancy. During this period, the embryo begins to develop. The basic organ systems begin to form. The heartbeat begins and can eventually be seen on an ultrasound image. Your baby's limbs, brain, spine, and digestive system begin to take shape. At this stage, the embryo resembles a bean-shaped structure.
During the second month of pregnancy, specifically between the sixth and eighth weeks, the embryo grows significantly. During this time, the embryo typically reaches a length of approximately 1.5 to 2.5 centimeters. Ultrasound scans at this stage can visualize the embryo and show the progress in its development.
Your baby is now the size of a raspberry.
Month 3: Development progresses
In the third month, your baby's development continues. The embryo is now called a fetus. The external genitalia begin to develop, although it is still too early to determine the sex. The fingers and toes are forming, and the eyelids are closing. The fetus can now move its muscles, even if you, as a mother, cannot yet feel them.
In the third month, at the end of the first trimester of pregnancy, the embryo continues to grow and reaches a considerable size. Typically, the embryo measures approximately 7 to 8 centimeters from head to toe during this period. Ultrasound examinations at this stage can already reveal a human-like appearance of the fetus.
Your baby is now the size of a lime.
Your baby's development during the first trimester of pregnancy is a fascinating process. In just three months, a tiny fertilized egg transforms into a fully developed fetus with organ function beginning to develop. During this time, it's crucial that you maintain a healthy lifestyle and receive prenatal care to ensure your baby's best possible development.
Typical complaints in the 1st trimester
Diarrhea in the 1st trimester of pregnancy
Diarrhea is one of the most common symptoms women experience during the first trimester. Various causes can trigger it, including hormonal changes, dietary changes, and a sensitive digestive tract. The following information will help you better understand and manage the symptoms:
- Causes: Hormonal changes, particularly the increase in the hormone progesterone, can slow digestion and lead to diarrhea. Furthermore, the sensitivity of the digestive tract to certain foods can increase.
- Symptoms: Diarrhea manifests as increased bowel movements, frequent, and loose stools. Accompanying symptoms may include lower abdominal cramps and bloating.
- Treatment: In most cases, diarrhea in the first trimester is harmless and doesn't require specific treatment. However, it's important to drink plenty of fluids to prevent dehydration. If the diarrhea is severe or lasts for more than a few days, you should consult your doctor.
Abdominal pain in the 1st trimester of pregnancy
Abdominal pain is another common symptom in the first trimester. Don't worry too much—in most cases, it's harmless and completely normal. Here's what you should know:
- Causes: The expansion of the uterus, hormonal changes, and the growth of the baby can lead to pelvic pain. This pain is often associated with so-called "stretching pain."
- Symptoms: The pain may manifest as pulling or stabbing in the lower abdomen. It is usually mild to moderate and often occurs in the first few weeks of pregnancy.
- Treatment: In most cases, abdominal pain is normal and doesn't require specific treatment. However, it's important to consult your doctor to make sure the pain doesn't indicate a serious problem.
- Note: If you are unsure about the cause of your abdominal pain, be sure to discuss it with your gynecologist!
Fatigue in the 1st trimester of pregnancy
Fatigue is another common symptom many women experience during the first trimester. This extreme exhaustion can be overwhelming, but it has a biological purpose.
- Causes: Increased production of progesterone and other hormones can lead to fatigue. Your body is working hard to support the pregnancy and promote your baby's growth.
- Symptoms: Fatigue manifests as a persistent feeling of exhaustion, even after adequate sleep. Women often feel weak and have difficulty concentrating.
- Treatment: The best way to deal with fatigue is to get plenty of rest. Scheduling short naps during the day and maintaining a balanced diet can be helpful.
Lack of motivation in the 1st trimester of pregnancy
Lack of motivation is another common symptom in the first trimester. This feeling can be both physical and emotional. We'll tell you what you need to know:
- Causes: Hormonal changes and the physical adjustment to pregnancy can lead to a lack of motivation. Emotional aspects such as worries and fears about the pregnancy and the upcoming life changes also play a role.
- Symptoms: Women may feel lethargic, lose interest in activities, and sometimes feel depressed or anxious.
- Treatment: Seek support from family and friends. Don't be afraid to seek professional help if needed to deal with emotional challenges. Regular exercise and a healthy diet can also help alleviate listlessness.
- Remember: Every pregnancy is unique, and not all women experience the same symptoms during the first trimester. If symptoms persist or are severe, you should always consult your doctor to ensure everything is okay and to discuss appropriate measures to relieve your symptoms.
pH value during pregnancy
During pregnancy, vaginal pH can fluctuate. A pH between 3.8 and 4.5 is considered normal for a healthy pregnancy.
However, a pH that's too high or too low can cause problems. For example, an elevated pH can be a sign of bacterial vaginosis, which can lead to complications such as premature birth. A low pH combined with symptoms such as itching or unpleasant odor can indicate a yeast infection that requires treatment.
It is therefore important to monitor vaginal pH during pregnancy and to test the pH yourself and/or consult a doctor if you experience changes or symptoms such as itching, burning or increased discharge.
Examinations in the first trimester of pregnancy
Meaning and process
The first trimester of pregnancy is a crucial time for the health of both mother and child. Therefore, regular medical checkups are essential to ensure the pregnancy is progressing well. Here you'll learn about the tests performed in the first trimester and why they're important.
- Confirmation of pregnancy:
The first step is to confirm pregnancy with a blood or urine test. This test measures the hormone hCG, which is only produced in the body during pregnancy.
2. First ultrasound:
The first ultrasound usually takes place between the sixth and eighth week of pregnancy. This confirms the pregnancy and checks the position of the embryo in the uterus.
3. Blood tests:
Blood tests are performed to check hemoglobin levels, blood sugar, and blood type. Tests are also performed for infections such as HIV and syphilis, as they can affect pregnancy.
4. Ultrasound screening for genetic abnormalities:
Between the 11th and 13th weeks of pregnancy, a special ultrasound called the nuchal translucency test can be performed. It is used for the early detection of genetic abnormalities such as trisomy 21.
5. Prenatal care advice:
Your doctor will advise you in detail about the importance of folic acid, iron, and other nutrients to support your and your child's health.
6. Examination of the cervix:
In the first trimester, your doctor may perform a cervical exam to make sure it is stable and shows no signs of preterm labor.
Regular checkups during the first trimester allow you to identify potential risks early and ensure proper prenatal care. They also provide an opportunity to discuss any questions and concerns to make your pregnancy as comfortable and healthy as possible. Remember that every pregnancy is unique, and your doctor will tailor the tests to your individual needs.
