The second trimester begins. Some early symptoms may improve, fetal growth becomes more noticeable and movement is increasingly coordinated even if you cannot feel it yet.
Approximately weeks 14-17
Medical note: Pregnancy months are approximate, while clinical follow-up relies on gestational weeks. This content is educational and does not provide diagnosis or an individualized treatment plan. Concerning symptoms or high-risk pregnancy require clinical review.
Month 4 covers approximately weeks 14 through 17. Some women begin to feel better as nausea and fatigue improve, while appetite and energy may gradually return.
Your baby continues growing quickly. Bones, muscles and the nervous system develop, movement becomes increasingly coordinated and your pregnancy bump may become more noticeable.
This information is educational and does not provide diagnosis or an individual treatment plan. Bleeding, fluid leakage, severe pain, fainting, severe headache with vision changes, fever or severe shortness of breath requires medical assessment.
Saudi Ministry of Health pregnancy-month mapping places weeks 14, 15, 16 and 17 in month 4.
Gestational weeks remain more precise for clinical care because ultrasound and screening windows are defined by weeks.
Explore week 14, week 15, week 16 and week 17.
As the uterus grows upward out of the pelvis, the abdomen and waist may become more visibly pregnant.
There is no single normal bump size at this stage. Body shape, height, weight, previous pregnancies and uterine position all influence appearance.
During weeks 14 to 17, fetal body proportions gradually become more balanced and facial features continue developing.
Bones continue hardening, muscles develop and arm and leg movements become more coordinated. Hands, feet and fingers become more defined.
Nervous-system development continues, and by the later part of the month hearing structures are progressing while fat begins developing beneath the skin.
The baby is already moving, but maternal awareness of those movements varies considerably.
Saudi Ministry of Health information notes that first-time mothers commonly notice movement around 18-20 weeks, while women who have been pregnant before may notice it earlier, sometimes around 13-16 weeks.
Some women therefore describe fluttering or bubble-like sensations during month 4, while others feel nothing yet. Not feeling movement during this month does not by itself indicate a problem.
Many women begin to look more obviously pregnant during month 4, but timing varies widely.
A later pregnancy may show earlier than a first pregnancy. Fetal wellbeing cannot be assessed from bump size alone.
As the uterus grows, the ligaments supporting it stretch. This can produce brief pulling or sharp discomfort on one or both sides of the lower abdomen, especially with sudden movement, coughing or standing quickly.
Mild intermittent discomfort can occur, but severe or persistent pain, particularly with bleeding, fever, dizziness or fluid leakage, requires medical assessment.
As the uterus grows and body mechanics change, some women begin experiencing lower back discomfort.
Regular suitable movement, comfortable footwear, posture changes and avoiding prolonged standing may help. Severe or sudden back pain or neurological symptoms need assessment.
External genital structures may sometimes be visible on ultrasound during month 4, but accuracy depends on gestational age, fetal position, image quality and examiner experience.
Later ultrasound, particularly the anatomy scan, often provides a clearer view.
The routine detailed anatomy scan usually comes just after month 4.
Saudi Ministry of Health guidance places the second routine ultrasound between 18 and 22 weeks, which begins in month 5 under this month mapping.
The scan assesses fetal growth and anatomy and reviews structures such as major organs and placental location according to the clinical examination.
Month 4 is therefore a good time to plan or book the upcoming anatomy scan for its appropriate window.
Testing depends on previous screening, medical history, age, earlier results and the clinical pathway being used.
In selected cases, clinicians may discuss AFP testing or other second-trimester screening.
A quad screen may also be used in some screening pathways. These are screening tests rather than definitive diagnoses, and they are not required for every pregnancy.
Amniocentesis is a diagnostic procedure and is not a routine test for everyone.
It may be discussed after an appropriate gestational age when there is a clinical reason, such as a screening result, family history or another indication identified by the care team.
Decisions should follow genetic or obstetric counselling that explains potential benefits, risks and alternatives.
Appetite may improve as early nausea eases, but pregnancy does not require simply doubling food intake. Quality and variety remain more important.
Include suitable protein, vegetables and fruit, whole grains, calcium-containing foods, iron-containing foods and adequate fluids.
Continue supplements recommended by your clinician and avoid starting high-dose vitamins, iron or herbal products without appropriate advice.
Regular suitable activity can be appropriate in an uncomplicated pregnancy.
Walking or pregnancy-appropriate exercises can be considered according to your health and previous fitness.
Stop activity and seek advice for bleeding, severe dizziness, significant pain, unusual shortness of breath or fluid leakage.
As the abdomen grows, pillows may help support your body and improve comfort.
If lying flat on your back makes you feel dizzy or unwell, change position. If you wake on your back, simply move into a comfortable position.
Continue your scheduled prenatal appointments even if nausea and fatigue have improved.
Follow-up may include review of weight, blood pressure, symptoms, previous test results and planning the upcoming anatomy ultrasound.
High-risk pregnancy or chronic illness may require a different schedule.
Use the pregnancy week-by-week guide for more precise timing.
Month 5 begins at week 18. The likelihood of noticing fetal movement increases and the important 18-22 week anatomy-scan window begins.
Continue to month 5 of pregnancy or go directly to week 18.
