26 Weeks Pregnant: Symptoms, Baby Development and What to Expect

At 26 weeks pregnant you are about 6 months along in the second trimester, with about 14 weeks to go, and your baby weighs about 2 pounds while glucose screening and Rh planning top your to-do list.

At 26 weeks pregnant your baby’s eyes are getting ready to open and your baby can hear your voice. You may be noticing more kicks, a sore back and harder nights.

Every clinical detail below was read in October 2026 on the primary sources named in the text.

26 Weeks Pregnant at a Glance

How the weeks are counted. Mayo Clinic says your due date is found by counting ahead 40 weeks from the start of your last period, so you are not actually pregnant for the first week or two of that count. That is why Mayo describes week 26 as 24 weeks after conception. MedlinePlus says a first trimester ultrasound gives an idea of your due date, so if an early scan moved your dates, use your provider’s dates.

Is 26 weeks the second or third trimester? Second, by every source we checked. They only disagree about when it ends:

Your care is the same on every calendar. See our second trimester guide.

Your Baby’s Development at 26 Weeks

Do babies open their eyes at 26 weeks? Not quite yet. By Mayo Clinic and Nemours KidsHealth, the eyes are developed and getting ready to open in the next couple of weeks.

How Big Is Your Baby at 26 Weeks?

Two primary sources give a week 26 figure. Both measure crown to rump (head to bottom), and their numbers differ, so both are printed.

Nemours KidsHealth says the legs are tucked under and cannot be measured, and that weight gain continues steadily until birth.

Neither page explains the gap, so treat both as rough averages; healthy babies vary. Neither offers a fruit comparison for week 26, so we have not added one.

26 Weeks Pregnant Symptoms

• Back pain: Nemours KidsHealth says more than half of pregnant women have back pain caused by the belly’s growth, weight and hormones. Walking, swimming or stretching may help.
• Trouble sleeping: Nemours KidsHealth calls this time of pregnancy the “perfect storm” for sleep problems: leg cramps, indigestion and a growing belly.
• Heartburn and indigestion: MedlinePlus says digestion slows during pregnancy, which can cause heartburn that is often worse at night.
• Leg cramps: if one wakes you, MedlinePlus suggests pressing your feet hard against the wall or standing on the affected leg.
• Swelling: Cleveland Clinic lists some swelling in your hands, feet and ankles as a common second trimester change. Extreme swelling of the hands or face is a CDC urgent warning sign.
• Skin changes: Nemours KidsHealth says hormones can cause dry skin, oily skin or both, and patches of darker skin called melasma. Cleveland Clinic adds stretch marks and a dark line down the belly (linea nigra).
• Your belly button: Nemours KidsHealth says it may flatten out or stick out more as the uterus grows, returning to normal after birth.
• Other second trimester changes: Cleveland Clinic lists round ligament pain, varicose veins, hemorrhoids, and bleeding gums and nosebleeds or congestion (due to hormones).

What about tightening? Cleveland Clinic says to call for regular tightening or pain in your lower abdomen or back that happens more than four times in an hour. See what contractions feel like.

Your Body and Belly at 26 Weeks

At 26 weeks most bumps are easy to see, but size and shape vary. See pregnant belly by month.

• Belly checks at visits: MedlinePlus says your provider will measure your abdomen at second trimester visits to see if your baby is growing as expected.
• Movement: Mayo Clinic says that around 20 weeks you might be able to feel your baby move. Now, Nemours KidsHealth says your baby may answer sounds with movement.
• Exercise: Cleveland Clinic suggests trying to exercise for about 20 minutes a day, names walking and swimming as some of the safest choices, and advises avoiding contact sports and activities where you could fall.

Is a lot of movement at night normal? MedlinePlus lists more movement at night as a common reason sleep gets harder. Movement that slows or stops is a reason to call right away (CDC).

Prenatal Care, Tests and Appointments Around Week 26

MedlinePlus and Cleveland Clinic say visits are usually monthly (every four weeks) in the second trimester. MedlinePlus says your provider will weigh you, check your blood pressure, measure your abdomen, possibly test your urine, and check your vaccinations.

About the glucose test. MedlinePlus says a high first result leads to a longer fasting test, and people at high risk may be tested earlier.

About vaccines. The CDC page (updated October 7, 2026) also says a COVID-19 vaccine during pregnancy can protect you and your baby from severe illness. Guidance changes, so confirm timing with your provider.

Is there a 26 week ultrasound? None of these sources schedules a routine scan this week. MedlinePlus says you should have an ultrasound around 20 weeks, and Cleveland Clinic describes the second trimester ultrasound as a check of your baby’s anatomy.

What to Do This Week: A Simple Checklist

• Confirm your glucose screening is booked or done before the end of week 28.
• Know your blood type. If you are Rh negative, ask when your antibody screen and RhoGAM shot are planned.
• Ask about the Tdap vaccine at your next visit. The CDC window opens at week 27. In October, ask about flu too.
• Start babyproofing in small steps. Nemours KidsHealth suggests covering outlets, removing choking hazards, installing smoke alarms and planning how to block off stairs.
• Save your provider’s after-hours number in your phone and read the warning signs at the end of this guide.

Sleep at 26 Weeks Pregnant

MedlinePlus says a growing baby makes a good position hard to find, and lists bathroom trips, a faster heart rate, shortness of breath, aches, heartburn, stress, vivid dreams and night movement as other reasons.

Sleep position. Cleveland Clinic’s second trimester advice is to sleep on your side instead of your back, because it is best for circulation. If you wake up on your back, it says not to worry: your body will usually prompt you to move. MedlinePlus (not tied to a week) says to try your side, ideally the left, that switching to the right is fine, and that it is best not to sleep flat on your back.

• Use pillows for support: MedlinePlus suggests pillows under your belly or between your legs, and a bunched-up pillow or rolled-up blanket at the small of your back. See how to use a pregnancy pillow.
• Plan the evening: cut back on soda, coffee and tea, and avoid a lot of fluids or a big meal within a few hours of bed (MedlinePlus).
• Skip sleep aids: MedlinePlus says not to take any sleep aids, including over-the-counter medicines and herbal products. Read can you take melatonin while pregnant.

For Partners: How to Help at 26 Weeks

• Talk to the bump. Nemours KidsHealth says the baby can hear voices from outside.
• Go along to the glucose test if you can. There is a wait between drinking the liquid and the blood draw.
• Take on the jobs that strain a sore back: laundry baskets, groceries, low cupboards and anything heavy.

Looking Ahead: What Comes Next

• Week 27: the CDC’s Tdap window opens, and by Mayo Clinic’s count this is the last week of the second trimester. See 27 weeks pregnant.
• Week 28: MedlinePlus says Rh negative patients may need RhoGAM around 28 weeks, and the usual glucose window closes.
• The third trimester: our third trimester guide covers the final stretch.
• Weeks 32 to 36: the CDC’s RSV vaccine window, during September to January.

When to Call Your Provider

Possible signs of preterm labor. Call your provider right away for any of these (Cleveland Clinic, MedlinePlus):

• Regular tightening or pain in your lower abdomen or back that happens more than four times in an hour (Cleveland Clinic).
• Any fluid leaking from the vagina, since leaking amniotic fluid may mean labor is starting (Cleveland Clinic). See signs of leaking amniotic fluid.
• Unusual or severe cramping or abdominal pain (Cleveland Clinic), or moderate or severe cramping or low belly pain (MedlinePlus).
• Any vaginal bleeding (MedlinePlus, Cleveland Clinic).
• More vaginal discharge than usual, or discharge with an odor; fever, chills or pain when you urinate (MedlinePlus).

Urgent maternal warning signs. The CDC’s Hear Her campaign says to seek medical care immediately for any of these and to say that you are pregnant:

• A headache that won’t go away or is severe.
• Vision changes, fainting, or dizziness that keeps happening.
• A fever of 100.4 F (38 C) or higher.
• Extreme swelling of your hands or face.
• Trouble breathing, chest pain, or a fast or irregular heartbeat.
• Severe nausea and vomiting.
• Severe belly pain that doesn’t go away.
• Your baby moving less, or movement stopping.
• Vaginal bleeding that is more than spotting, fluid leaking, or foul-smelling discharge.
• Severe swelling, redness or pain in a leg or arm.
• Overwhelming tiredness that is sudden.
• Thoughts about harming yourself or your baby.

If something just isn’t right, talk to your provider (CDC). If you cannot reach your provider quickly, go to labor and delivery or the nearest emergency room, and call 911 in an emergency. This article is general education, not medical advice.
