HOW PREMOM TRACKS YOUR PREGNANCY
Personalized to your pregnancy, week by week
Premom uses your estimated due date or the first day of your last menstrual period — to build a week-by-week pregnancy timeline that's specific to you. From there, it keeps you informed every step of the way, from your first trimester to delivery day.
Enter your due date
Tell Premom your estimated due date or your last menstrual period (LMP). Our pregnancy week calculator does the math — figuring out exactly how many weeks pregnant you are and where you sit in your current trimester.
Get weekly updates
Every week, Premom delivers a personalized update — your baby's size and development, what's changing in your body, common pregnancy symptoms to expect, and what to ask your provider at your next visit.
Log, learn, and prepare
Track symptoms, moods, weight, and bump photos as your pregnancy progresses. Premom builds your full pregnancy history — and prepares you with trimester checklists, expert-reviewed articles, and prenatal appointment reminders.
Don't miss a single week
Every Premom update is built around exactly where you are in your pregnancy — from week 5 to week 40 and beyond.
KEY FEATURES
Everything you need, from week 5 to week 40
Eight tools built into one free pregnancy app — covering baby development, symptom tracking, prenatal appointment management, and everything in between. Designed for first-time moms, experienced parents, and partners who want to follow along.
Follow your baby's development from conception to delivery. Each week, Premom shows your baby's approximate size and weight — with familiar comparisons like a poppy seed at week 5 or a cantaloupe at week 25 — along with the key fetal development milestones happening that week: organ formation, senses, and movement.
Frequently Asked Questions About Pregnancy Tracking
How does Premom calculate my pregnancy week?
Premom uses either your estimated due date or the first day of your last menstrual period (LMP) — the same approach your obstetrician uses. From there, our pregnancy week calculator figures out exactly how many weeks pregnant you are and references standardized fetal growth and development models used in obstetric care to give you accurate, week-by-week updates.
Can I use Premom in my first trimester?
Absolutely. Many users open Premom the moment they see a positive pregnancy test. The first trimester comes with the most questions — about symptoms, food safety, what to expect at your first appointment — and Premom's trimester guides and expert library are built to support you from around week 5 onwards.
Does Premom replace prenatal care?
No. Premom is designed to complement your prenatal care, not replace it. It's a tracking and education tool — it can't diagnose, treat, or substitute for advice from your healthcare provider. What it can do is help you stay organized between visits and bring better notes, symptom logs, and questions to every appointment.
Is Premom a free pregnancy tracker app?
Yes. Premom's core pregnancy tracking features are free on iOS and Android — including week-by-week updates, baby size comparisons, symptom logging, appointment reminders, and trimester guides. Premom Premium adds personalized weekly insights, advanced symptom analytics, exclusive expert content, and an unlimited bump journal.
