Pregnancy Weight Gain Calculator

Let’s talk about something that comes up a lot during pregnancy and no, it’s not baby names or birth plans. We’re talking about weight gain. It’s one of the most common concerns for mums to be, yet also one of the most confusing and emotionally loaded.

We at BellyBelly believe pregnancy is not perfect, it’s learning, it’s being empowered and supported. So we created our Pregnancy Weight Gain Calculator. A free, easy tool that is designed to help you keep track of how much weight gain is best for your body, your pregnancy, and your pace.
Move away from the outdated charts and varied opinions on social media. Our pregnancy weight gain calculator uses the latest guidelines from credible health organisations. Whether you’re at your first three months or approaching your third trimester, our calculator tells you about what a healthy weight gain range is, not from someone else’s pregnancy but for you.

Here’s how it works: you’ll enter your pre-pregnancy weight, your current weight and height, and your current week of pregnancy. The calculator then uses your BMI to determine a personalised weight gain range, week by week. It’s that simple, but, this isn’t about unrealistic expectation or judgment. Pregnancy is not a one size fits all experience and weight gain is influenced by so many things: metabolism, genetics, hunger, activity level, water retention, and even cravings (yes, midnight snack you have).
The aim of our pregnancy weight gain calculator is not to inform you of what you “ought” to weigh, but to give you evidence based information that enables you to feel in control and confident. It’s about listening to your body, not fixating on the number on the scale. And if you’re gaining a bit more or a bit less than the calculator recommends? That’s fine too. Your own instincts are always the best guide, along with regular checks with your midwife or doctor.

We know that every pregnancy is different. Some mums feel great and full of energy the whole time, while others are coping with morning sickness, pelvic cramps, or just plain tiredness. That’s why our guide is here to help, not to judge — and that’s why so many mums come to BellyBelly for authentic, honest advice that takes them through every step.

So if you’re wondering, “Am I gaining too much? Not enough? What’s normal?”, relax you’re in good hands. Try out our pregnancy weight gain calculator today and find out how to track your journey with knowledge, compassion, and a whole lot of self-love.
