How Many Months Pregnant Are You At 30 Weeks?

At 30 weeks pregnant, you are in the seventh month and third trimester. You are around ten weeks away from your due date.

How Big Is Your Baby At 30 Weeks?

This week, your baby is as big as a large cabbage (1). The fetal weight in this week is 15.71in (39.9cm) in length and 2.91lb (1.319kg) in weight (2). Around 1.5l of amniotic fluidiClear, yellowish liquid surrounding and protecting the developing fetus during pregnancy. surrounds the baby, eventually reducing as the baby grows and takes more space inside the uterus (3).

Baby Development At 30 Weeks

Here is how the baby is developing this week:

Body organsDevelopment
Skin (4)Looks smoother and starts accumulating fat under the skin. It is the baby’s white fat
LanugoThe fine hair covering the body starts shedding. Some babies are born with some hair on their shoulder, ear, and back
Brain (5)The brain tissues are developing and forming wrinkles to accommodate more brain cells.
Bone marrowIs producing more red blood cells.
Nervous system (6)Developed and starts controlling some body functions.
Lungs (7)Are still developing, but are capable of breathing.
EyelidsBegin to open and close.
HeadMight be full of hair.
FingersDeveloped and baby can suck thumb.
Ears (8)Developed and the baby can react to loud sounds.
Tongue (9)Taste buds are developed.

Fetal position and movements: The baby may be in a head-up or head-down position, as there is still some space left for the baby to move. As the due date approaches, the baby will attain the optimum position. After 36 weeks, the fetal presentation remains static. However, the space inside the womb can be comparatively crunched in a twin pregnancy. The kicks get stronger by this week and can be felt frequently.

Symptoms You May Experience In The 30th Week Of Pregnancy

As the pregnancy proceeds, new symptoms may develop, even as the earlier ones remain. Symptoms that you may experience this week include:

  • Weight gain: An average maternal weight gain of one to two pounds per week during the third trimester of pregnancy is considered safe, as recommended by the American Pregnancy Association (APA) (10). However, the recommended weight gain rates for women with BMI less than 18.5 and greater than 24.9 usually range between 0.5 and one pounds. Gaining weight within the healthy range during pregnancy can help prevent complications like gestational diabetes and preeclampsia.
BMI18.5 – 24.925 – 29.930 and Above
Recommended weight gain (lb)18- 2716- 2410-187-14
  • Heartburn: The gastric juices forced upward into the esophagus by the growing uterus may cause you to experience heartburn.
  • Trouble sleeping: Owing to body aches, frequent urination, leg cramps, and anxiety, you can sometimes have difficulty sleeping well.
  • Swelling: Swollen feet and ankles during this time may occur from water retention in the body.
  • Fatigue: It is common as the body works extra and needs additional nourishment.
  • Difficulty in breathing: The pressure exerted by the growing uterus on the diaphragm can make it hard to breathe at times.
  • Backache: The extra weight of the baby puts pressure on the lower back, causing pain in that region.
  • Frequent urination: The bladder is compressed by the growing uterus, which increases the urgency to urinate more often.
  • General discomfort: You may be more uncomfortable due to the increased weight from the growing belly, which may restrict your movements and cause symptoms such as back pain, frequent urination, and shortness of breath.

Julia Goolia, a mom of three, reflects on the general discomforts she experienced during the 30th week of her third pregnancy. She notes, “Exhausted some days, high on life for others. Harder to get up from lying down, difficult to carry my children around, and still with the pressure ‘down there’ that makes me feel like the baby is sitting directly on my private parts… I think I’m more tired this time around, but still feeling really good for being in the final stretch of pregnancy (i).”

  • Feet changes: Fluid retention and reduced blood circulation can cause swelling in the feet. In addition, increased levels of maternal hormones might cause loosening of the joints, which in turn may cause the feet to grow bigger (11) (12).
  • Varicose veins: Swelling of the veins in the legs due to increased blood flow to the lower part of the body leads to varicose veins.
  • Mood swings: Mood swings during pregnancy are common, and the changes in the hormonal levels may cause you to experience them in the third trimester (13).
  • Bloating and gas: As the digestion process slows down, the food remains longer in the digestive tract, creating gas and making you feel bloated.
  • Constipation: The digestive tract relaxes due to the progesteroneiA female reproductive hormone that plays a vital role in menstruation, pregnancy, and breastfeeding. hormone, which slows digestion and causes constipation.
  • Braxton Hicks contractions: These irregular and spontaneous contractions help your body prepare for labor and delivery.
  • Stretch marks: They become prominent in the later part of the pregnancy, such as the sixth or seventh month, due to the stretching of the belly from the growing uterus (14).

These symptoms result in specific physiological and psychological changes as well.

If you are experiencing vivid or disturbing dreams during the third trimester, do not worry. Dreams may be a way for your body to cope with the stress of pregnancy and hormonal changes (1).

30 Weeks Pregnant With Twins

If you are 30 weeks pregnant with twins, you may expect the following besides the other common symptoms (15):

  • Weight gain of 1.5lb per week, which may differ from person to person
  • Frequent tiredness from otherwise easy activities
  • More Ob/Gyn visits for fetal monitoring to ensure the health of both fetuses, by regularly checking fetal heart rate and overall well-being.
  • Preterm labor since a twin pregnancy may increase the chances of premature birth. According to studies conducted by researchers from Sidney Kimmel Medical College and Icahn School of Medicine at Mount Sinai, twins account for 20.0% of all preterm deliveries. Among these twin pregnancies, 60.0% of cases result in delivery before 37 weeks of gestation, while 10.7% of twins are born before 32 weeks of gestation.

30 Weeks Ultrasound

At the 30th week ultrasound, you may see the following visuals and fetal development milestones (16) (17):

  • Spine and ribs of the baby
  • Umbilical cord with its blood vessels
  • Baby’s skin appears smooth and less wrinkly

When To Call The Doctor

If you notice any of the following symptoms, ensure to call the doctor right away (18):

  • Pelvic pain with or without cramping
  • Fever (100.4 degrees or higher)
  • A headache that doesn’t subside even after taking Tylenol (acetaminophen)
  • Persistent nosebleeds
  • Pain or a burning sensation while urinating
  • Persistent cramps
  • Dizziness
  • Sudden weight gain (two pounds in one week).
  • Sudden bleeding or spotting
  • Sudden stoppage of fetal movement

If the symptoms are normal, go for a regular OB/GYN check-up.

Your Ob/Gyn Visit

During the visit, the obstetrician may:

  • Measure the symphysis fundal height
  • Check blood pressure and weight
  • Advise a urine test to check for sugar or protein level
  • Suggest an ultrasound to track the fetal development, especially in the case of multiple pregnancies or high-risk pregnancy.

Other tests that are done during this week:

  • For pregnant women from areas where Syphilis (Sexually Transmitted Infection) is prevalent, the doctor may advise a syphilisiA sexually transmitted bacterial disease, typically causing sores in the genital and oral regions, linked to fetal complications. diagnostic test between 28 and 32 weeks of pregnancy and during delivery.
  • A biophysical profile is done in the case of twin or multiple pregnancies. It is a combination of an ultrasound and a non-stress test to gauge fetal growth.
  • 75gm oral glucose tolerance test if not done at 28 weeks.
  • Along with the medications or supplements suggested by the doctor, you should also follow a healthy lifestyle for a healthy pregnancy.

Frequently Asked Questions

1. What does a super active baby in the womb mean?

Generally, it is believed that an active baby is a healthy baby. These movements promote healthy bone and joint development. In such a case, you need not worry and stay relaxed and healthy.

2. Can I deliver in 30 weeks?

The survival rate of fetuses born between 28 and 32 weeks is around 80 to 90% (19). Some babies may be transferred to NICU for the necessary neonatal care for a day or two.

3. What does a 30-week baby do in the womb?

At 30 weeks, your baby has developed its reflexes and can be seen sucking its thumbs (17). During this time, they mostly keep their eyes closed and turn less. However, at 30 weeks, your baby will kick and poke more (20).

4. What are the signs of preterm labor at 30 weeks?

A few signs of preterm labor to look out for at 30 weeks of pregnancy are (21):

  • Period-like cramps
  • Pelvic pressure
  • Vaginal discharge with or without blood
  • Painless or painful contractions
  • Low back pain

5. How many hours does a baby sleep in the womb at 30 weeks?

It has been shown that usually unborn babies in the womb sleep for about 90 to 95% of the day (22); however, after 18 weeks of pregnancy, unborn babies may prefer to nap in the womb while their mother is awake since movement can help lull them to sleep (23).

6. How do I know if my baby is head-down at 30 weeks?

To determine your baby’s position in utero, you can ask your healthcare provider to perform an ultrasound or to feel your abdomen manually. However, it is important to note that the baby’s position can frequently change in the last weeks of pregnancy, so the position at 30 weeks does not necessarily indicate the probable fetal position at birth.

The little kicks get stronger as you approach the 30th-week pregnancy. The baby weighs about 2.8lb, can suck thumb, and may react to loud sounds. Much of the space inside your belly is occupied, which may cause digestion problems, frequent urination, body pains, and difficulty breathing. An enlarged belly, swollen breasts, and stretch marks are some changes you experience at 30 weeks pregnant. Stay relaxed, avoid sleeping on your back, and follow prenatal check-ups and medication instructions. Seek medical help if you experience abnormal pain, vaginal bleeding, or contractions.
