You're staring at the fridge again. Everything looks boring, or worse, everything looks like a potential risk. One minute you're told to "drink for two," and the next, you're reading a terrifying forum post about how herbal tea might cause early contractions. It’s exhausting. Honestly, figuring out what to drink when you're pregnant shouldn't feel like a high-stakes chemistry exam, but here we are.
Hydration is basically the engine of your pregnancy. Your blood volume increases by about 50% during these nine months to support that tiny human. If you aren't drinking enough, you feel it—the headaches, the brain fog, and the dreaded pregnancy constipation that no one warns you about enough.
The Boring Truth About Water
Let's get the obvious one out of the way. Water is king. You’ve heard it a million times, but it’s true for a reason. According to the American College of Obstetricians and Gynecologists (ACOG), you should be aiming for about 8 to 12 cups (64 to 96 ounces) of water every single day.
Is that a lot? Yeah. It’s a ton.
If you’re struggling with morning sickness, plain water can actually taste metallic or just plain gross. It's a real thing called dysgeusia. If that's you, try ice-cold water. Sometimes the temperature change numbs the taste buds enough to get it down. Or add a squeeze of lemon. Or lime. Or cucumber slices.
Why the extra fluid?
It isn't just for you. It’s for the amniotic fluid. That fluid needs to stay at a healthy level to protect the baby and help their lungs and kidneys develop. Plus, water helps your body flush out waste products from your own cells and the baby’s. It’s basically a plumbing job.
The Caffeine Question: Can You Have Your Latte?
This is where people get really heated. You'll have one person tell you that a single drop of coffee is "poison" and another tell you they drank three cups a day and their kid is a genius.
The middle ground is where the science actually lives.

The general consensus from organizations like the March of Dimes and ACOG is to cap your caffeine intake at 200 milligrams per day. To put that in perspective, a standard 8-ounce cup of brewed coffee usually has around 95 to 165 mg. A shot of espresso is about 63 mg.
But be careful.
A "medium" coffee at a chain shop isn't 8 ounces; it's often 16 or 20. Suddenly, you've doubled your limit without realizing it. High caffeine intake has been linked in some studies to lower birth weights and an increased risk of miscarriage, though the data on the 200mg limit specifically suggests that level is generally safe for most people.
If you can’t give up the ritual, try a "half-caf" or switch to a dark roast. Fun fact: dark roast actually has slightly less caffeine than light roast because the beans are roasted longer.
Milk and Plant-Based Alternatives
Calcium is non-negotiable right now. If you don't consume enough calcium, your body—being the selfless machine it is—will literally leach it from your own bones to give it to the baby.
- Cow’s Milk: It’s a powerhouse. Vitamin D, protein, and calcium. Just make sure it’s pasteurized. Raw milk is a hard "no" because of the risk of Listeria, which is devastating during pregnancy.
- Soy Milk: Probably the best plant-based alternative for protein content. Most brands are fortified with calcium and Vitamin D, making it nearly identical to dairy in terms of benefits.
- Almond Milk: It’s basically nut water. It tastes great in cereal, but it has almost zero protein. If you choose this, make sure you're getting your protein elsewhere.
- Oat Milk: Creamy and delicious. It’s higher in carbs, which can actually be a lifesaver if you’re struggling to keep food down and need some easy energy.
What to Drink When You're Pregnant and Nauseous
Morning sickness is a liar. It doesn't just happen in the morning. For many, it's a 24/7 internal battle. When you can't keep a cracker down, drinking becomes your primary source of survival.
Ginger Ale and Ginger Tea
Ginger is one of the few "old wives' tales" backed by actual clinical evidence. Studies published in the Journal of Maternal-Fetal and Neonatal Medicine have shown that ginger is effective at reducing the severity of nausea.

But check the label.
A lot of commercial ginger ales are just high-fructose corn syrup and "natural flavors" with zero actual ginger. Look for ginger beer (non-alcoholic, obviously) or steep fresh ginger root in hot water.
Electrolyte Drinks
If you've been vomiting, you're losing more than just water. You’re losing salt, potassium, and magnesium. Pediatric drinks (like Pedialyte) or sports drinks (like Gatorade or Powerade) can help. Just watch the sugar. Too much sugar can actually make some people feel more nauseous or lead to a "crash" later.
Coconut Water
Nature’s Gatorade. It’s packed with potassium. It’s also surprisingly good at settling an acidic stomach. If the taste bothers you, mix it with a little bit of pineapple juice.
The "Danger Zone": What to Avoid Completely
It’s not just about what you should drink, but what you need to ghost for a while.
- Alcohol: There is no "safe" amount of alcohol during pregnancy. Fetal Alcohol Spectrum Disorders (FASD) are 100% preventable by abstaining.
- Unpasteurized Juices: That "fresh squeezed" cider at the farmer's market? Skip it. If it hasn't been pasteurized, it can carry E. coli or Salmonella. Your immune system is slightly suppressed right now, so these bugs hit you way harder.
- High-Sugar Sodas: Occasional treat? Fine. But making it your primary fluid source increases the risk of gestational diabetes and excessive weight gain.
- Energy Drinks: These are a "hard pass." They often contain huge amounts of caffeine and unregulated herbal blends like ginseng or taurine. We just don't have enough data to say they're safe.
Herbal Teas: The Gray Area
This is where it gets tricky. "Natural" doesn't always mean safe.
Peppermint tea is generally considered safe and is great for heartburn (which will likely plague you in the third trimester). Raspberry leaf tea is often recommended by midwives to "tone the uterus," but most doctors suggest waiting until the third trimester to start drinking it, as it may stimulate mild contractions.

Avoid teas with large amounts of:
- Hibiscus (linked to potential issues in some animal studies)
- Lemongrass (in large medicinal amounts)
- Licorice root (can affect blood pressure)
When in doubt, stick to the basics: Rooibos, fruit-based teas, or a weak ginger tea.
Making a Hydration Plan
If you're finding it hard to stay hydrated, don't just "try harder." Use a strategy.
Some women find that "front-loading" their water helps. Drink the bulk of your fluids before 4:00 PM. This way, you aren't waking up six times a night to pee (you'll probably still wake up twice, but it’s better than six).
Invest in a straw. It sounds silly, but people tend to sip more consistently through a straw than they do from the rim of a glass.
Actionable Next Steps
- Audit your caffeine: Check the actual ounce size of your coffee mug. If it's a 12-ounce mug, you're likely getting 150mg of caffeine in one go.
- Buy a 32-ounce water bottle: Your goal is to finish three of these a day. Having a visual marker makes it much easier to track.
- Check your urine: It sounds gross, but it's the best indicator. You want it to look like pale lemonade. If it’s dark like apple juice, go drink 16 ounces of water right now.
- Stock the freezer: Make "hydration popsicles" out of diluted fruit juice or coconut water for those days when even the thought of liquid makes you queasy.
- Talk to your OB: If you truly cannot keep any liquids down for more than 12 hours, call your doctor. Hyperemesis gravidarum is a serious condition that often requires IV fluids.
Staying hydrated is a job. It's probably the most boring part of pregnancy, but it’s also one of the most impactful things you can do for your energy levels and your baby's environment. Keep it simple, keep it pasteurized, and keep a bottle of water within arm's reach at all times.
