At 30 weeks pregnant, your baby is gaining weight, practicing breathing, and responding to sounds. You might experience new or stronger symptoms as your body adapts to your baby’s growth.
You’re now 30 weeks pregnant—welcome to the home stretch! With only 10 weeks left, your baby is growing rapidly, practicing movements, and preparing for life outside the womb. At this stage, you might notice more pronounced symptoms like back pain or Braxton Hicks contractions as your body adjusts. Let’s dive into what’s happening with your baby, your body, and how to prepare for the exciting weeks ahead.

30 weeks pregnant symptoms
Here are common symptoms you may experience at 30 weeks:
- Back pain: The growing bump and shift in posture can strain your lower back.
- Braxton Hicks contractions: Irregular contractions may increase in frequency as your body practices for labor.
- Swelling (edema): Mild swelling in your feet or hands is common due to fluid retention.
- Heartburn: Hormonal changes and the baby pressing on your stomach can cause acid reflux.
- Shortness of breath: Your growing uterus may press against your diaphragm, making breathing more difficult.
30 weeks pregnant symptoms not to ignore
- Severe swelling: Particularly in the face or hands, it could indicate preeclampsia.
- Regular, painful contractions: Could be a sign of preterm labor.
- Reduced baby movements: If your baby’s movements decrease, contact your provider immediately.
Braxton Hicks contractions vs true labor
| Aspect | Braxton Hicks Contractions | True Labor |
|---|---|---|
| Frequency | Irregular, not progressively closer together | Regular intervals, getting closer together |
| Intensity | Weak, often described as mild discomfort | Increases in strength over time |
| Duration | Short, usually lasting less than 30 seconds | Longer, lasting 30-70 seconds per contraction |
| Location of Pain | Felt mainly in the front of the abdomen | Starts in the back and radiates to the front |
| Effect of Movement | Stops or decreases with activity or a change in position | Continues regardless of movement or position changes |
| Cervical Changes | Does not cause dilation or thinning of the cervix | Causes the cervix to dilate and thin out (effacement) |
Your body at 30 weeks pregnant
At 30 weeks, your uterus is about four inches above your belly button, and your bump is larger and rounder. Weight gain by this stage typically ranges between 20-25 pounds, though this can vary based on individual factors.
30 weeks pregnant belly
Your belly at 30 weeks reflects your baby’s growth, and you may notice more pronounced kicks and rolls. As your bump grows, you may experience itching or tightness in your skin—moisturizing regularly can help.
30 weeks pregnant in months
You are 7.5 months pregnant, with approximately 10 weeks left until your due date, which is 40 weeks and 0 days.
Baby development at 30 weeks of pregnancy
At 30 weeks, your baby’s lungs and digestive system are still developing. They’re practicing breathing movements, and their brain is developing more complex neural connections. Your baby can now open and close their eyes and may react to light, sound, and touch.
30-Week baby size
The 30-week-old baby’s size is about 16 inches long and weighs around 3 pounds, similar to the size of a cabbage. Your baby is continuing to gain fat, which helps regulate their body temperature after birth.
30 weeks pregnant ultrasound
A 30-week ultrasound may be performed if your provider needs to monitor growth, check the baby’s position, or assess amniotic fluid levels. You might see your baby’s facial expressions and movements more clearly during this scan.

30-Week preemie
A baby born at 30 weeks has a survival rate of over 95% with appropriate medical intervention. By this week, the baby’s lungs have started producing surfactant, a substance that helps keep their air sacs open, which improves their chances of breathing independently as they grow.
However, they will still require NICU care for issues like feeding through a tube, maintaining a stable body temperature, and possible respiratory support. If a preterm birth is anticipated before 34 weeks, it is common practice to administer antenatal steroids while you are still pregnant. These steroids help the baby’s lungs mature and function more effectively outside the womb. They are typically given between 24 and 34 weeks when delivery during this period is expected or planned.
Babies at this stage typically weigh around 3 pounds (1.4 kilograms) and are at risk for conditions like jaundice or infections, which are closely monitored by healthcare providers.
Tests to expect at 30 weeks pregnant
At this stage, your provider will perform routine tests to monitor your health and your baby’s development:
- Blood pressure check: To screen for hypertension or preeclampsia.
- Fetal heartbeat and movements: Your provider will listen to your baby’s heartbeat and ask about movement patterns.
- Urine test: Screens for protein, which can indicate preeclampsia.
- Fundal height measurement: Monitors the size of your uterus to ensure proper growth.
- Blood tests (if needed): Checks for anemia or other concerns.
These tests help ensure both you and your baby are healthy as you approach delivery. Always discuss any new symptoms or concerns with your provider.
Health tips and self-care at 30 weeks pregnant
- Support your back: Use a lumbar cushion when sitting and practice good posture to reduce back pain.
- Stay hydrated: Drinking water helps manage swelling and supports your increased blood volume.
- Practice breathing exercises: These can help with shortness of breath and prepare you for labor.
- Track baby movements: Monitor your baby’s activity to ensure they’re healthy and active. Recognizing what is normal for your baby’s movements is essential, as every baby is unique. According to updated guidelines from the American College of Obstetricians and Gynecologists (ACOG) in 2021, routine kick counting is no longer recommended as the primary method for fetal monitoring due to limited evidence of its benefits and the potential to increase anxiety. However, if you notice a significant decrease in your baby’s usual activity, it’s important to contact your physician or clinic promptly.

Questions from the Femia community
What are the best positions for labor?
Upright positions like squatting or kneeling can use gravity to help labor progress. Side-lying positions are also effective, especially if you need to conserve energy. Discuss options with your provider to find what works best for you.
How much weight is average to gain?
Average weight gain by 30 weeks is around 20-25 pounds. However, it varies depending on your pre-pregnancy weight. Your provider will monitor your weight to ensure it’s within a healthy range for your baby’s development.
Why do I feel mild contractions?
These are likely Braxton Hicks contractions, which are irregular and painless. They’re a normal part of pregnancy as your body practices for labor.
The bottom line
At 30 weeks pregnant, your baby is growing rapidly, and your body is preparing for the final stretch of pregnancy. Stay proactive by tracking symptoms, maintaining good posture, and discussing any concerns with your provider.
