You can drink coffee when you’re pregnant, but most medical guidelines say to keep total caffeine under about 200 mg per day (roughly one 12 oz cup of brewed coffee, or one “regular” cup plus a smaller one). Many people also choose to cut back further, especially in the first trimester or if they feel jittery, anxious, or have trouble sleeping.

Key guidelines

  • Most obstetric groups consider moderate caffeine (under 200 mg per day) unlikely to increase miscarriage or preterm birth risk.
  • That’s about:
    • 1 standard 12 oz coffee, or
    • 1–2 small cups of home-brewed coffee, depending on strength.
  • Caffeine is also in:
    • Black/green tea, energy drinks, cola, and chocolate, which all count toward your daily limit.

Possible risks and nuances

  • High caffeine intake in pregnancy has been linked in observational studies to:
    • Higher miscarriage risk and fetal heart rhythm issues at high doses.
* Slightly smaller birth size, even at intakes below 200 mg/day in some newer research.
  • Caffeine crosses the placenta and is found in amniotic fluid and fetal blood, and babies clear it more slowly than adults.
  • For some pregnant people, caffeine worsens:
    • Nausea, palpitations, anxiety, insomnia, increased urination, and dehydration risk.

How much is in common drinks?

  • Brewed coffee (8 oz): ~95–100 mg caffeine.
  • Espresso (1 oz shot): ~63 mg; a 2–3 oz espresso drink can still fit under daily limits.
  • Black tea (8 oz): ~40–50 mg.
  • Decaf coffee (8 oz): usually ~2 mg, but not zero.

What doctors and forums are saying now

  • Professional bodies still broadly use the “under 200 mg per day” guideline, but stress individual discussion with your own clinician.
  • Some newer studies and charities call for clearer messaging and possibly more caution, because even moderate caffeine may slightly affect birth size.
  • On pregnancy forums, many users share:
    • Having one morning cup and feeling judged by strangers despite staying within medical guidance.
* Others choosing to cut caffeine completely to feel extra safe or because it worsens nausea.

Practical tips if you’re pregnant

  • Good questions to ask your prenatal provider:
    • “Is one cup of coffee a day okay for me given my pregnancy and medical history?”
    • “Should I cut back further in the first trimester?”
  • Ways to reduce caffeine without quitting coffee entirely:
    • Switch to half-caf or decaf for second or third cups.
* Alternate with herbal teas that are known to be safe in pregnancy (ask your provider which).
