What Happens At My 24 Week Visit?

We’re continuing our series on routine prenatal care around here! With the bulk of the laboratory testing, physical exam and an established due date, routine obstetric care moves into a prevention, assessment and education cycle.

In case you missed the other posts so far…here are the links!

What are the components of the 24 week visit?

Let’s break it down!

Review of symptoms or patient concerns

These are any symptoms that have occurred since the last visit with the provider that the patient desires to discuss with the provider. An example is: “I think I have a yeast infection because there are white chunks coming out of my vagina and it itches.” Or, “I had a yeast infection two weeks ago but I used Monistat over the counter and my symptoms disappeared. Was this okay to do?

Because it’s a routine visit, the review of system questions are targeted to pregnancy unless the woman’s history or questions indicate investigation and follow up. These questions are generally the same at every visit for the rest of pregnancy.

The questions are:

After the routine questions, I have some favorite questions that I like to ask during this visit. A lot of these questions are centered around a return to energy (although fatigue and extra naps are still very normal), return to normal appetite, and changes in sleep habits or patterns. I also like to review weight gain, nutrition and exercise.

These are some of the questions I ask at the 24 week visit:

The Screening

Screenings are usually completed in a number of fashions – sometimes by the tech asking the woman questions or by having the woman fill out a piece of paper.

Screening for psychosocial factors is an important part of prenatal care. Some risk factors (i.e. homelessness, loss of job, smoking, drinking, moving…) are present before prenatal care and some factors happen during the pregnancy or postpartum. To increase the number of opportunities to provide timely intervention, support or referral, ACOG & AAP (2017) recommend screening on a regular basis during prenatal care and documentation of each screening in the prenatal record.

If the woman has a history of depression or anxiety, reports new symptoms of either depression or anxiety, or is on medication for mood management, a screening is appropriate to assess her mood and risk. ACOG (2015) only recommends screening once during the perinatal period and once a the postpartum period.

Screening tools vary across practices and regions of the world. In the United States, the most common tools used for screening in pregnancy at the EPDS or the PHQ (PHQ-2 or PHQ-9).

It is always appropriate to ask that the provider review your screening results with you. A screening tool is very valuable. And sometimes a woman may feel uncomfortable talking about her mood even though she knows something isn’t feeling quite right. A positive screening is a flag for your provider to ask more questions and also review options for support, counseling or resources.

The Exam, Lab Testing, and Ultrasounds


Once the pregnancy is established, the exam is limited to checking for normal progression of the pregnancy.

Laboratory testing

There are very few labs that are done around this visit.


If the anatomy scan was not reviewed at the 20 week visit, the report is typically reviewed at the 24 week visit.

Read all about the scan on the 20 Week Visit in case you missed it!

Some high risk pregnancy disorders (chronic hypertension, diabetes, intrauterine growth restriction) continue to have regular ultrasounds throughout the pregnancy to assess the baby’s growth and well-being. Low risk pregnancies tend to only have the dating scan and the anatomy scan – but this varies greatly from practice to practice and city to city.

The Education

The 24 week visit is a sweet spot for education. You’re not quite into the bulk of the third trimester and you still have quite a bit of energy before the uterus really increases in size. I find that this time period is equally education for things that are current questions, issues or discomforts (back pain, traveling, mental health, or vaccines) or it’s a time to talk about about things that are right around the bend (28 week labs, vaccines (again), preterm labor and breastfeeding).

These are the common areas of education, but the sky really is the limit and varies greatly from provider to provider.

These are the ones that I think are best for the gestational age!

Back pain

When it comes to back pain in pregnancy, it’s usually not a matter of if, but when.

Back pain is extremely common in pregnancy. The pain is from a number of factors, but the root cause is an enlarged uterus. There are hormones in pregnancy that cause your ligaments to stretch and soften more easily than when you are not pregnant.

There are a number of interventions that you can try to reduce the discomfort:

If back pain continues or worsens during pregnancy, consider a consultation with a physical therapist (Cedars-Sinai, 2021; National Health Service, 2021).


The World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) recommend that children start breastfeeding within the first hour after birth and that breastmilk is the only source of food for the first six months of the baby’s life. At six months of age, infants should begin to eat food while continuing to breastfeed for up to two years, or as long as desired by mother and infant (World Health Organization, 2021).

Breastfeeding can provide a child half of a child’s nutrients (food) between the ages of 6 and 12 months and up to a third of nutrients from 12 to 24 months (World Health Organization, 2021).

Babies that are breastfed are:

Mothers that breastfeed are:

Babies that are not breastfed are:

Mothers that do not breastfeed are:

In the age of the Internet, there are some amazing websites about breastfeeding. These are some of my favorites:

Other great breastfeeding resources can be found under ‘breastfeeding’ on the RESOURCES page.

preterm labor

Preterm labor is defined as:

Regular contractions with cervical change before 37 weeks of age (ACOG & AAP, 2017) .

The pathophysiology behind preterm labor is still unknown. Possible causes of preterm labor include hemorrhage of the placenta (known as placental abruption), uterine over-distention (such as in twin pregnancies), cervical insufficiency (a short or dilated cervix), hormone changes, infection or inflammation (ACOG & AAP, 2017).

On of the biggest risk factors for a preterm birth is a prior preterm birth. Women that have had a preterm birth before are 1.5 to 2 times more likely to have another preterm birth (ACOG & AAP, 2017).

It’s important to review preterm labor signs and symptoms at second and third trimester visits. A woman should also have a phone number to contact a provider or nurse and a place to go for evaluation should she have any of the signs or symptoms (ACOG & AAP, 2017).

The signs and symptoms include (see infographic above):

This March of Dimes video offers a great overview of preterm labor signs…

travel during pregnancy

Cohort studies have shown that air travel in pregnancy is not associated with adverse outcomes. Domestic travel up to 36 weeks of gestation is generally allowed by airlines but internal airlines may have different guidelines. The most common emergencies in pregnancy occur in the first and third trimesters (ACOG & AAP, 2017).

Air travel is not recommended for any pregnant woman that has medical or pregnancy conditions that could worsen from air travel or that may require emergency care (ACOG & AAP, 2017).

Women that travel by air or take long road trips should:

Zika is the only mosquito borne illness that has been associated with birth defects in infants. Birth defects from Zika include microcephaly (a small head) and brain abnormalities. Pregnant women should avoid travel to areas with Zika; if unable to avoid such areas, women should use insect repellant with DEET, wear clothing that covers the skin, and attempt to stay in air conditioned or screened in areas. ACOG and the CDC (Centers for Disease Control and Prevention) also recommend treating clothing with permethrin (ACOG & AAP, 2017).

If your spouse travels to an area with Zika, the CDC recommends either abstinence from intercourse or condom use during the woman’s pregnancy (ACOG & AAP, 2017).

Regarding COVID-19, the most up to date precautions for travelers are here.

ACOG has an excellent site for Travel in Pregnancy.

mental health

About 1 in 10 women reported an episode of depression in the past year (Centers for Disease Control and Prevention [CDC], 2020).

About 1 in 8 women experience symptoms of postpartum depression (CDC, 2020).

ACOG recommends that women be screened for depression at least once during the prenatal period (ACOG & AAP, 2017). Many clinics screen more often but screenings do vary from clinic to clinic and practice to practice. Most clinics use a validated depression screening called the Edinburgh Postnatal Depression Scale or an EPDS.

This screening produces a score that allows a provider to see if a woman screens positive for mild, moderate or severe depression.

Depression can consist of a few symptoms or a lot of symptoms. Symptoms of depression can include:

There are lots of risk factors for depression or anxiety. Sometimes, you may start your pregnancy with some risk factors. Sometimes, you may start your pregnancy without any risk factors, but then your partner loses their job, you move across the country and you have a traumatic delivery. All of these risk factors increase your risk for postpartum depression or anxiety.

Not sure if you have risk factors? Start with this tool by Postpartum Support International! You can print it out, fill it out, and take it into your provider to review together at a visit. The resources are all free and you can access them all from your couch!

Do you already have depression, anxiety or other mental disorders?

A glucose and an anemia screening are recommended around 28 weeks of pregnancy. The glucose test is a screening for gestational diabetes and the anemia screening is exactly that – a screening to make sure you are not deficient in iron or have another type of anemia.

The glucose test is a sugary drink generally provided by the lab or the office staff. The drink is 50 grams of glucose. The woman has about 10 minutes to drink the bottle (they usually taste like orange, red or yellow gatorade flavors). About an hour after she finishes the bottle, a blood sample is taken to check your blood sugar level. If you level is abnormal, or high, a follow up test is recommended.

The follow up test is a 3 hour test with a 100 gram drink. The 3 hour glucose test is considered the diagnostic test for gestational diabetes – this means that if your 3 hour test is abnormal, you will likely receive the diagnosis of gestational diabetes in pregnancy.

More information from ACOG about routine tests in pregnancy is available here.

At 28 weeks, the TDaP vaccine (tetanus-diptheria-pertussis) is recommended for pregnant women. The actual range for the vaccine is between 27 to 36 weeks. When the vaccine is given during this time, the mother’s immune system creates antibodies in response to the vaccination and these antibodies are transferred across the placenta to the baby (CDC, 2021).

The vaccine reduces the risk of a baby less than 2 months old from getting whooping cough by 78% (CDC, 2021).

TDaP vaccination for pregnant women is supported by a number of profession organizations. You can read their statements of support here:

Lastly, it is not routine to test the number of antibodies a woman has to whooping cough and it is not known what level of immunity is protective against whooping cough. Because of this, a TDaP vaccine is recommend during every pregnancy – even if your pregnancies are only one to two years apart (CDC, 2021).

The Follow Up

Whew, we made it through all that information…but where do you go from here?

The follow up information is just as important as the rest of the visit!

Here’s a list to review with a woman and her family before leaving the clinic!

Other goodies…

For providers and women, the Share with Women Handouts cannot be beat for many discomforts and conditions of pregnancy.

ACOG’s Resources for You (Frequently Asked Questions about pregnancy/women’s health) and‘s Prenatal Resources are also excellent resources.

For any recommendations about books to read during pregnancy, I like to start with these recommendations, but a full list is available on the BOOKS & MORE page!

And this is great blog for new mamas to follow on topics regarding your baby’s health…

Whew! That’s a wrap. Remember, this is only a guide for the 24 week visit. Providers and patients work together to address the needs at the time of the visit. And, a lot of prenatal education is reviewed again and again!
