Get trimester-by-trimester clarity on what to expect, what to monitor, and when something needs a closer look.

At a Glance

  • Many symptoms are common but can feel alarming — tracking when they happen matters.
  • Bleeding, severe pain, and unusual discharge should never be ignored.
  • When in doubt, inform your doctor. It’s always safer to get checked early.

First Trimester: New, Strange, and Often Normal

Your body is adjusting fast to hormonal changes. Common symptoms include:

  • Nausea or vomiting
  • Fatigue
  • Mood shifts
  • Mild cramping or lower back pain
  • Breast tenderness
  • Dizziness

Inform your OB immediately, if you experience:

  • Heavy bleeding
  • Bright red bleeding

  • Severe abdominal pain, especially if one-sided
  • Fever over 38°C
  • Painful urination or cloudy urine

Second Trimester: More Stable, Still Watchful

Many women feel better now — nausea eases, energy returns, and appetite improves. Common symptoms include:

  • Round ligament pain (brief sharp groin pain with movement)

  • Leg cramps or mild swelling in the ankles

  • Occasional Braxton-Hicks contractions

Inform your OB if you notice:

  • Persistent headaches or vision changes
  • Severe pain that doesn’t ease with rest
  • Leaking fluid or watery discharge

These may be early signs of preeclampsia, infection, or preterm labor.

Third Trimester: Baby Is Growing, So Are the Demands

Normal symptoms now include:

  • Shortness of breath
  • Frequent urination
  • Mild back pain
  • Stronger Braxton-Hicks contractions
  • Trouble sleeping

     

However, call your OB if you experience:

  • Decreased fetal movement (fewer than 10 kicks in 2 hours)
  • Sudden severe abdominal pain
  • Vaginal bleeding
  • Persistent vomiting
  • Severe swelling or headache
  • Contractions before 37 weeks

What to Do Next: Guidance for Pregnant Moms

  • Keep a symptom tracker or note app to monitor patterns over time, and discuss with your OB
    during check-up.
  • If symptoms escalate quickly (bleeding, severe pain, fever), go directly to the ER or your delivery
    hospital.
