Weekly Pregnancy Tracker: Follow Your Pregnancy Day by Day
Track your pregnancy weekly: save your last period date once and see your week and day, trimester, days left, and baby size. Fully private, no account.
Key Takeaways
- The pregnancy tracker saves your last period date in your browser once, and on every visit shows your current week and day, trimester, days left until birth.
- It shows your due date in both Gregorian and Hijri, your baby's approximate size, a progress bar, and a countdown to the nearest important milestone.
- No account or sign-up needed; your data never leaves your device and you can delete it with one click.
- The tracker is an organizational and educational tool, and does not replace your doctor and your regular check-up schedule.
How does the pregnancy tracker work?
The idea is simple: you enter the first day of your last menstrual period just once, and your browser saves it in your device's private storage (localStorage). Every time you visit the tracker page, the site automatically calculates: how many days have passed since that date, which week and day you are in now, which trimester of pregnancy, and how many days remain until your expected due date.
The calculation uses the same Naegele's rule used in the pregnancy calculator: 280 days from the first day of your period. The difference is that the tracker does not just give you the number once; it keeps it alive: every day you open the page you find your numbers updated, your baby's size for this week, and the nearest upcoming milestone in your journey.
Because all calculations happen inside your browser in JavaScript, the site never sends your period date or any personal information to any server. That is by design: your health information is sensitive, and its place is on your own device.
What are the benefits of tracking your pregnancy weekly?
First: staying on top of check-ups. Many tests are tied to specific weeks: the detailed anatomy scan between weeks 18 and 22, the gestational diabetes test between 24 and 28, and the Group B strep swab before birth. The tracker reminds you of the next milestone before it arrives so you never miss one.
Second: understanding what is happening to your body. When you know you are in week 24, for example, you understand why you feel short of breath or heartburn; knowledge reduces anxiety and turns frightening symptoms into expected stages.
Third: preparing ahead. Each trimester has its preparations: the first for vitamins and the first visit, the second for setting up the baby's room, the third for the hospital bag and the birth plan. Seeing the countdown makes preparation gradual, not sudden.
Fourth: documenting the journey. Nine months pass quickly; having a weekly record of your baby's size and your pregnancy progress creates a beautiful memory you can share later.
What will you find on your dashboard?
Your personal dashboard shows on every visit:
- Your current week and day precisely (example: week 23 + 4 days).
- The trimester you are in (first, second, or third).
- Your expected due date in both Gregorian and Hijri.
- The days remaining until birth and a visual progress bar.
- Your baby's size this week in a familiar comparison (a fruit or vegetable) with approximate length and weight.
- The next milestone with a countdown to it: end of the first trimester, the week of medical viability (24), start of the third trimester (28), full-term (37), then the due date.
- A direct button to your week page with details on fetal development and tips for that week.
Your privacy: your data never leaves your device
We designed the tracker with a privacy-first philosophy: we ask for no name, no email, and no phone number, and we create no account for you. The date you enter is saved in your browser's local storage on your device only; it is sent to no server and shared with no third party.
This means two practical things: first, if you open the site from another device or browser you will not find your data there; each device is independent. Second, you can delete your data permanently at any moment with one button on the dashboard itself, or by clearing your browser data as usual.
One tip: if you use incognito mode, your browser may not keep the data between sessions; use normal mode to keep your tracking.
Start tracking in three steps
Step one: enter the first day of your last menstrual period (Gregorian) in the field above. Step two: press the save button; your dashboard will appear instantly with your current week and due date. Step three: bookmark the page and revisit it weekly; you will find everything updated automatically without re-entering.
If you want to change the date later (for example after your ultrasound corrects it), the change button is right there on the dashboard.
The tracker's limits and when to see your doctor
The tracker is an excellent organizational tool but it is estimating by nature: it relies on Naegele's rule, which assumes a 28-day cycle, and your actual due date may differ by days or weeks. A first-trimester ultrasound is the most accurate reference when in doubt.
And the tracker does not replace danger signs: vaginal bleeding, leaking fluid, severe headache with vision changes, stopping of fetal movement after you got used to it, or sharp abdominal pain. If any of these occur, call your doctor immediately and do not wait for your regular check-up.
Frequently Asked Questions
Is my data safe in the pregnancy tracker?
Completely; the date is saved in your device's browser only (localStorage) and sent to no server. We ask for no name, no email, and create no accounts.
Do I need to create an account to use the tracker?
No; it works directly with no sign-up. Enter the date once and your browser will remember it on every visit from the same device.
What should I do if I forgot my last period date?
Check your period-tracking app if you use one, or ask your doctor; a first-trimester ultrasound can estimate the pregnancy age accurately when the date is unknown.
Does the tracker work on my phone and tablet together?
Data is saved in each browser separately; enter the date once on each device you use.
How do I delete my data permanently?
Press the Delete my data button on the dashboard, or clear your browser data; the date disappears instantly, and we never had a copy of it anyway.
My cycle is irregular; is the tracker useful for me?
It gives you a useful approximate framework for weekly follow-up, but rely on your doctor's ultrasound for exact test and appointment dates.
Does the tracker remind me of test appointments?
It shows you the nearest upcoming milestone with a countdown to it (end of the first trimester, week 24, start of the third trimester, full-term), so you can plan your visits around them.
Does the tracker replace doctor visits?
Never; it is only an organizational and educational tool. Regular medical follow-up and ultrasounds cannot be replaced by any app.
