Pregnancy increases your daily water requirement by about 10 fl oz above your personal baseline. That's on top of adjustments for your weight, activity level, and trimester. Generic "drink 8 glasses" advice doesn't cut it when you're growing a person.

Why hydration matters for pregnant women

Supports amniotic fluid levels

Adequate hydration directly maintains amniotic fluid, which cushions and protects your baby throughout pregnancy.

Reduces swelling and cramping

Counter-intuitive but true: drinking more water helps reduce the water retention that causes pregnancy swelling and leg cramps.

Prevents preterm contractions

Dehydration is a common trigger for Braxton Hicks and, in severe cases, early labor. Consistent hydration reduces this risk.

Eases morning sickness

Small, frequent sips — especially in the first trimester — can help settle nausea and keep electrolytes balanced.

How Thirsty Girls helps

Features designed for your specific needs.

Pregnancy-adjusted daily goals

Your goal automatically includes the +300ml (≈10 oz) recommended increase for pregnancy, on top of your weight and activity baseline.

Gentle, supportive AI coach

Choose a coaching personality that meets you where you are — whether you need encouragement, soft nudges, or someone to just check in.

Smart reminders that adapt

Reminders target the hours you tend to forget — not just a random ping at 2pm. Especially helpful when morning sickness disrupts your usual routine.

Streak & mood tracking

Log how you're feeling alongside your water intake. Patterns in your mood and hydration become visible over weeks — useful context for OB visits.

Common questions

How much water should I drink while pregnant?

General guidance is about 10 cups (80 fl oz) per day, but your actual need depends on your weight, activity level, and how much you sweat. Thirsty Girls calculates a personalized goal using your specific stats plus the recommended pregnancy bonus.

Does the app know I'm pregnant?

Yes — during onboarding you can select "pregnant" as a health consideration. Your daily goal is then calculated with the appropriate increase built in.

What if I struggle to drink enough due to morning sickness?

The app's quick-log feature lets you log small amounts throughout the day. Even 2–4 oz at a time adds up. Your AI coach will celebrate consistent small wins.

Can I use this alongside my OB's advice?

Absolutely. Thirsty Girls is a habit tool, not a medical device. Always follow your doctor's specific guidance — the app just helps you actually hit the goal they give you.
