First Trimester Pregnancy Checklist (Weeks 1–13)

1: Schedule Your First Prenatal Visit

Once you get a positive pregnancy test, book your first appointment with a healthcare provider. This usually happens between 6–10 weeks of pregnancy.

Why it matters:

• Confirms your pregnancy
• Sets your due date
• Starts prenatal care and lab tests

Your provider will guide you on what to expect in the coming months.

2: Start Taking Prenatal Vitamins

Prenatal vitamins are crucial in the early stages. Folic acid, in particular, helps prevent neural tube defects during fetal development.

Tips:

• Look for a supplement with folic acid, iron, DHA, and calcium
• Take them daily—even before your first appointment if possible

Starting early boosts your baby’s brain and spinal development.

3: Review Your Medications and Lifestyle

Talk to your doctor about any current medications, supplements, or habits that could affect your pregnancy.

What to check:

• Prescription drugs and over-the-counter medications
• Herbal supplements
• Alcohol, smoking, and caffeine intake

Making healthy lifestyle changes early protects both you and your baby.

4: Learn About Early Pregnancy Symptoms

Understanding what’s normal helps reduce stress. Common first trimester symptoms include:

• Nausea and morning sickness
• Breast tenderness
• Fatigue
• Mood swings

If anything feels extreme or unusual, consult your doctor.

5: Start a Pregnancy Journal or App

Tracking your journey can be fun and functional. Use a pregnancy app or journal to log milestones, symptoms, and questions for your doctor.

Benefits include:

• Staying informed week-by-week
• Monitoring baby’s growth
• Keeping track of appointments

This also makes a wonderful keepsake.

6: Schedule Mid-Pregnancy Ultrasound

Around 18–20 weeks, you’ll have a detailed anatomy scan. This ultrasound checks your baby’s development and may reveal the gender (if you choose).

Expect:

• A longer appointment
• Checking organs, spine, limbs, and placenta
• A peek at your growing baby

This is a major milestone and often very emotional!

7: Start Shopping for Maternity Clothes

As your belly grows, your regular clothes might feel tight. It’s time to stay comfy and confident.

Checklist for essentials:

• Maternity jeans or leggings
• Supportive bras
• Loose tops and dresses
• Belly band (optional)

Comfort matters as your body changes shape.

8: Begin Baby Registry & Nursery Planning

Use this time to build your baby registry and start organizing the nursery. You’re likely feeling more energetic and excited—take advantage!

Focus on:

• Crib, mattress, and changing table
• Diapers, wipes, and clothing
• Car seat and stroller

Ask other moms or use registry guides to stay on track.

9: Look Into Childbirth & Parenting Classes

It’s never too early to prepare for delivery and beyond. Sign up for childbirth, newborn care, and breastfeeding classes in your area or online.

Why it's useful:

• Reduces fear about labor
• Helps partners feel more involved
• Builds parenting confidence

Learning in advance helps you feel empowered.

10: Monitor Fetal Movements

You’ll soon begin feeling those precious first kicks. Pay attention and share any concerns with your provider.

Pro tip: Once movement becomes consistent (usually around week 24), start kick-counting each day to monitor baby’s health.

11: Prepare Your Birth Plan

A birth plan outlines your preferences during labor and delivery. Discuss it with your doctor or midwife.

Include things like:

• Preferred delivery method
• Pain relief options
• Who will be in the room
• Delayed cord clamping or immediate skin-to-skin

It helps set expectations and reduces anxiety.

12: Pack Your Hospital Bag

Don’t wait until the last minute! Aim to pack around 34–36 weeks.

Hospital bag essentials:

• ID, insurance, and birth plan
• Comfortable clothes and socks
• Toiletries
• Phone charger
• Baby’s going-home outfit
• Snacks

Keep the bag near the door—or in the car.

13: Install the Car Seat

Before you’re allowed to leave the hospital, you must have a properly installed car seat.

Tips:

• Choose a rear-facing infant car seat
• Practice installing it ahead of time
• Check for recalls or expiration dates

Many fire stations offer free installation help.

14: Attend Weekly Checkups

Your prenatal visits will become more frequent in the final weeks. Your provider will monitor your cervix, baby’s position, and overall progress.

Expect during appointments:

• Blood pressure checks
• Belly measurements
• Questions about contractions or signs of labor

These visits help ensure a safe delivery for both mom and baby

15: Plan for Postpartum Recovery

It’s easy to forget that you need care too. Stock up on postpartum essentials and prepare mentally for recovery.

Helpful items:

• Maxi pads and peri bottles
• Nursing bras and breast pads
• Pain relievers and stool softeners
• Comfortable clothes and snacks

Ask for help when you need it. Rest is vital!
