Try to aim for 3 liters, but be prepared to make the bathroom your second home, haha! Seriously, the baby uses your bladder as a trampoline, but keep chugging that water anyway.
I was always worried if I was drinking enough water or too much! I aimed for 2.5 liters because I was scared of low amniotic fluid. Just sip slowly throughout the day so you don't feel too bloated.
I felt so thirsty all the time during my pregnancy! I kept a 1-liter bottle with me and tried to finish 3 of those daily. It felt like a small achievement every time I stayed hydrated.
I personally tried to drink around 2.5 to 3 liters of water every day. It really helped me manage my digestion and kept me feeling hydrated, especially in the afternoons.
Aim for about 8 to 10 glasses, and you can add coconut water or fresh lemon juice if plain water feels boring. But if you have extreme nausea and can't keep liquids down, check with your doctor immediately.
