Pregnancy Week Tracker

Pregnancy week tracker

A 40-week pregnancy tracker you can write in.

Week-by-week grid showing weeks 1 through 40, the matching trimester, and the calendar date each week starts. A fillable notes box for every week wraps and grows to several lines — pick Large if you want twice the writing room.

Sample output
40-week pregnancy tracker table with week numbers, trimester labels and the calendar date each week starts
Week by week from your due date or LMP — trimesters labelled, a notes column for each week. The generator above builds yours from the options you choose.

Pregnancy tracker by week — dates from your due date

Enter the due date or the first day of your last period and the tracker lists all 40 weeks with the date each one starts and which trimester it falls in, plus a notes column for appointments and milestones. Print it as a keepsake or keep the filled PDF. The pregnancy & baby planning hub has the countdown and first-year calendars that go with it.

Tips for the best result

Use it as a keepsake. 40 weeks of notes turns into a real artifact. Print on cardstock, fill week-by-week, slip into a baby book at the end.

Mark appointments and ultrasounds in advance. Once you have the schedule, write all appointments into the right week — the tracker becomes your reference for "what's coming."

Take a weekly photo and tape it to that week. A 40-photo bump progression is one of the most valued artifacts of a pregnancy. Tape Polaroids or printed phone shots into the relevant week's row.

Don't worry about filling every week. Some weeks are eventful, some aren't. Blank weeks are fine and honest.

Frequently asked questions

Why 40 weeks instead of 9 months?
Pregnancy is conventionally measured in completed weeks from the first day of the last menstrual period (LMP), not from conception. That works out to about 40 weeks (280 days) for a full-term pregnancy — slightly longer than 9 calendar months. The week-based system is what doctors, books, and apps all use.
Should I enter my due date or my LMP?
Either works. The generator computes the calendar dates for all 40 weeks from whichever you provide — most pregnant people have one or the other handy. If you have an ultrasound-adjusted due date, prefer that over the LMP-based estimate; it's more accurate.
When are the trimester boundaries?
Conventionally: First trimester = weeks 1-12, Second trimester = weeks 13-27, Third trimester = weeks 28-40. The tracker labels each row with its trimester so the transitions are visible at a glance.
What can I write in each week?
Anything you'd want to remember: doctor appointments, ultrasound dates, weight, measurements, baby movement, symptoms, cravings, name shortlists, gifts received, who you told about the pregnancy, and the small private things that matter — first time you felt the baby kick, the conversation with your partner about names. It doubles as a keepsake.
Is this medical advice?
No — this is a calendar and journal template only. For medical questions, prenatal-care decisions, or symptoms that worry you, talk to your OB-GYN, midwife, or healthcare provider. Apps with prenatal-care guidance (BabyCenter, Ovia, What to Expect) are useful too.
Can I use this for a friend or family member's baby?
Yes — many grandparents, aunts, and friends print one to follow along with a loved one's pregnancy and to plan visits, showers, and the post-baby support window.
