What Symptoms Are Normal in the Third Trimester?
Mild swelling, Braxton Hicks contractions, and pelvic pressure are the three most common third-trimester symptoms, and all three are typically normal.
Swelling (edema) in your feet, ankles, and hands shows up as your body holds onto more fluid to support your baby, and it’s typically worse by evening. Braxton Hicks contractions, the irregular tightening across your belly, are your uterus practicing for labor; they ease with rest or movement, while real contractions intensify no matter what you do. Pelvic pressure builds as your baby drops lower and settles into position. Sudden swelling in your face or hands, especially paired with a headache or vision changes, is not part of this normal list (see Warning Signs, below) (ACOG, Mayo Clinic, Cleveland Clinic).
How Do You Know When Labor Starts?
You’re likely in true labor when contractions become regular, intensify over time, and don’t ease with rest, often alongside the bloody show and, in some cases, your water breaking.
A common benchmark is the 5-1-1 rule: contractions 5 minutes apart, lasting 1 minute each, for at least 1 hour. You may also notice the bloody show, pink or blood-tinged mucus discharge that appears as your cervix begins to efface and dilate, sometimes days before labor starts. Call your provider if your water breaks, your contractions match the 5-1-1 pattern, or you can no longer talk through a contraction (ACOG, Mayo Clinic, Cleveland Clinic).

What Symptoms Should You Never Wait Out?
A short list of symptoms, including a severe headache, vision changes, sudden swelling, reduced fetal movement, bleeding, or fluid leaking, should prompt a same-day call to your provider, even if everything else feels normal.
A severe or persistent headache, vision changes, upper-right abdominal pain, or sudden swelling in your face and hands can signal preeclampsia, a blood pressure condition that needs prompt evaluation. A distinct, sustained change in your baby’s movement, not just a quiet afternoon, is also worth a same-day call, along with vaginal bleeding, fluid leaking, fever, or abdominal pain that doesn’t fade (ACOG, Mayo Clinic, Preeclampsia Foundation).

If anything here feels uncertain, you don’t have to wait for your next scheduled appointment to ask. Reach your January care team by phone or text.
January is not an emergency service. If something feels urgent, call your provider or 911.
How Do You Manage Third-Trimester Symptoms While Still Working?
Track new or changing symptoms briefly instead of relying on memory, ask about early-morning or virtual appointment options if daytime scheduling is tight, and loop your manager or HR into your leave timeline earlier than feels necessary.
Prenatal visits get more frequent from here: Mayo Clinic notes checkups typically move to every 2 to 4 weeks early in the third trimester, then every 1 to 2 weeks starting around week 36 (Mayo Clinic), which adds up to real time away from your desk. A quick note on your phone each time something feels different gives your care team real information to work with, rather than asking you to recall a whole week from memory at your next visit. Leave paperwork, whether FMLA, short-term disability, or your company’s own policy, often takes longer to process than expected, so starting that conversation early gives you more room to plan rather than scramble.
Frequently Asked Questions
Is swelling normal in the third trimester?
Yes. Mild swelling in the feet, ankles, and hands is common due to increased fluid and blood volume, and it's usually worse by evening. Sudden swelling in the face or hands, especially with a headache or vision changes, needs same-day medical attention.
How do I tell Braxton Hicks from real labor contractions?
Braxton Hicks are irregular, don't intensify, and often ease with movement, rest, or hydration. Real labor contractions grow longer, stronger, and closer together over time and don't stop with a change in activity.
What is the 5-1-1 rule for contractions?
The 5-1-1 rule is a common guideline for when to head to the hospital: contractions 5 minutes apart, lasting 1 minute each, for at least 1 hour.
What does bloody show mean?
Bloody show is pink or blood-tinged mucus discharge that happens as the cervix effaces and dilates. It can appear days before labor or right as it starts.
What are the warning signs of preeclampsia in the third trimester?
Key signs include a severe or persistent headache, vision changes, upper-right abdominal pain, and sudden swelling in the face or hands. These require same-day medical evaluation.
When should I worry about reduced fetal movement?
A distinct, sustained change from your baby's usual movement pattern, not just a quieter afternoon, is worth a same-day call to your provider.
How often will I have prenatal appointments in the third trimester?
Visits typically happen every 2 to 4 weeks early in the third trimester, then every 1 to 2 weeks starting around week 36, until delivery.
Third trimester or not, you shouldn't have to figure this out alone. Talk to your January care team.
