1. How does the fetus develop in the first trimester?
Fetal position in the mother’s womb
During the first three months, the fetus develops rapidly. At this stage, the embryo is just beginning to form basic organs. By the end of the first trimester, the fetus measures about 6-7 cm, has a clear shape, and can make slight movements. Mothers usually cannot feel these movements yet, but development is progressing strongly.
Signs of healthy fetal development
Some signs indicating a healthy fetus during this stage include:
- Mild morning sickness that does not suddenly disappear
- Gradual weight gain of about 0.5–2 kg
- Clear fetal heartbeat detected by ultrasound
- No signs of bleeding or prolonged abdominal pain
If you experience any abnormal signs such as vaginal bleeding, severe abdominal pain, or dizziness, please visit a medical facility for timely examination.

2. Scientific nutrition and lifestyle

- Iron: prevents anemia
- Calcium and vitamin D: essential for fetal bone development
- Fiber: helps prevent constipation, a common problem in pregnancy
Some recommended foods during the first trimester include dark green vegetables, nutritious seeds, salmon, eggs, yogurt, bananas, and avocados.
Foods to avoid
Pregnant women should avoid certain harmful foods such as:
- Raw or undercooked seafood
- Unpasteurized cheese
- Unwashed raw vegetables
- Fermented foods that are not hygienic
Additionally, foods high in sugar and unhealthy fats should be limited to avoid excessive weight gain.
Daily lifestyle restrictions
- Avoid self-medication: do not take any medicine without doctor’s advice
- Avoid strenuous activities: heavy exercise or lifting heavy objects may harm the fetus
- Avoid exposure to harmful chemicals: stay away from hair dyes, insect sprays, and other toxic substances during this period
3. Sexual activity and exercise: yes or no?
Is sexual intercourse safe during pregnancy?
Yes, as long as there are no abnormal signs such as bleeding, abdominal pain, or history of miscarriage. However, pregnant women should consult their doctors if they have any concerns about sexual activity during pregnancy.
Should pregnant women exercise?
Light exercise such as walking, prenatal yoga, and meditation is very beneficial for both mother and baby. It helps improve health, mood, and prepares the body for childbirth. However, avoid high-intensity workouts.
4. Prenatal checkups and health monitoring
How many prenatal visits are needed in the first trimester?
Expecting mothers should visit the doctor at least 1–2 times during the first trimester to determine fetal age, check fetal heartbeat, and monitor fetal development. This helps doctors detect any issues early and provide timely treatment.
What ultrasound and tests should be done?
- Ultrasound to check fetal position and development
- Blood tests to check iron and vitamin levels
- Birth defect screening: this is the right time for screening tests like Double Test
Mothers should perform these tests as scheduled to ensure the health of both mother and baby.
5. Reliable sources of pregnancy knowledge
Pregnant women should refer to official information sources such as obstetricians, reputable medical centers, and medical literature to avoid misinformation. Attending prenatal classes is also very helpful for mental and physical preparation for pregnancy and childbirth.
