Pregnancy Checklist: What to Actually Do, Trimester by Trimester

July 9, 2026 · 11 min read · 6 sources cited

In short

A useful pregnancy checklist has three parts: what to do at your prenatal visits (labs, screenings, vaccines), what to change in daily life (prenatal vitamin, foods to skip, gentle movement), and what to set up before the baby comes home (a rear-facing car seat, a safe sleep space, a bag for the hospital). Most people see a provider about every four weeks until 28 weeks, every two weeks until 36 weeks, and weekly after that. Everything else — the swaddles, the bassinet, the freezer meals — flows from those three anchors.

There is no shortage of pregnancy checklists on the internet. Most of them are 200 items long, half of them are trying to sell you a swaddle, and by the second scroll you have quietly closed the tab. This one is different. It is short, it is honest about what is medically necessary versus what is nice-to-have, and every clinical claim on it traces back to a source you can click and read for yourself.

The real pregnancy to-do list has three parts: the medical care you get from your provider, the daily habits that keep you and the baby well, and the small handful of things that need to be set up at home before you bring a newborn into it. Here is what actually belongs on each one.

This is general information, not medical advice

Every pregnancy is different. Anything on this page about vitamins, vaccines, symptoms, or timing is worth running past your own OB, midwife, or family doctor — they know your history and can tell you what applies to you. If something feels off between visits, call them. That is what they are there for.

01The prenatal-care checklist (what your provider will handle)

The single most important thing on any pregnancy checklist is regular prenatal care. MedlinePlus — the National Library of Medicine's consumer health site — defines it plainly: "Prenatal care is the health care you get while you are pregnant. It includes your checkups and prenatal testing." Most people follow a schedule that looks like this: "Once a month for weeks 4 through 28; Twice a month for weeks 28 through 36; Weekly for week 36 until your baby is born."

Book that first appointment as soon as you have a positive test. At the first visit, MedlinePlus says your provider will "ask about your health history, including prior pregnancies; ask about your family's health history; do a complete physical exam, including a pelvic exam and Pap test." After that, "during most visits, your provider will most likely check your blood pressure and weight gain; measure your abdomen to check fetal growth; check the fetal heart rate."

What your prenatal appointments cover

  • First visit (weeks 6-10ish). Medical and family history, physical exam, dating the pregnancy, first round of blood and urine labs.
  • First trimester screening. Optional blood tests and an ultrasound around 11-13 weeks to screen for chromosomal conditions.
  • Anatomy scan (around 18-22 weeks). The mid-pregnancy ultrasound that checks the baby's organs and, if you want to know, sex.
  • Glucose test (24-28 weeks). Screens for gestational diabetes.
  • Tdap vaccine (27-36 weeks). Given every pregnancy to pass whooping-cough protection to the baby.
  • Group B strep swab (around 36 weeks). A quick swab that tells your team whether you need antibiotics in labor.
  • Weekly checks from 36 weeks on. Position, heart rate, blood pressure, cervical checks if you want them.

You do not need to memorize this. Your provider will walk you through each step in order. What matters is showing up — the whole point of prenatal care, as MedlinePlus puts it, is that "it lets your provider spot health problems early."

02The daily-habits checklist

Between visits, the checklist gets short. It is not about doing more — it is about doing a few specific things consistently.

Take a prenatal vitamin every day

The one supplement no pregnancy checklist can skip is folic acid. MedlinePlus explains why: "For women who may get pregnant, it is really important. Getting enough folic acid before and during pregnancy can prevent major birth defects of her baby's brain or spine." The MedlinePlus pregnancy nutrition page puts the number at 600 micrograms per day during pregnancy, and adds that "it is hard to get this amount from foods alone, so you will most likely need to take a supplement that contains folic acid."

A standard prenatal vitamin covers that, plus the extra iron (27 mg/day), calcium (1,000 mg/day for adults), and vitamin D (600 IU/day) MedlinePlus flags as needing to go up during pregnancy. Any drugstore prenatal that hits those numbers is fine — you do not need the boutique version.

Eat mostly what you'd normally eat, minus a short list

The list of foods to avoid is real but shorter than the internet makes it sound. Per MedlinePlus, skip alcohol entirely, avoid high-mercury fish like shark, swordfish, and king mackerel, and stay away from undercooked meats and eggs, unpasteurized dairy and soft cheeses, raw sprouts, and unwashed produce. Caffeine gets a limit, not a ban: MedlinePlus notes that "drinking high amounts of caffeine may be harmful for your baby" and suggests keeping it under 200 mg a day — roughly one 12-ounce cup of drip coffee.

One quiet warning worth repeating: MedlinePlus notes that too much vitamin A supplementation can cause birth defects, so don't stack extra vitamins on top of your prenatal without your provider signing off.

Stay active in a low-key way

MedlinePlus keeps this one simple: "Stay active. Physical activity can help you stay strong, feel and sleep better, and prepare your body for birth." Walking counts. Swimming counts. Prenatal yoga counts. The point is regular movement your body already knows — not launching a new intense program at 20 weeks.

Clear every medicine with your provider — even the boring ones

MedlinePlus is direct: "Always check with your provider before you start or stop any medicine. This includes over-the-counter medicines and dietary or herbal supplements." Ibuprofen, herbal teas, that supplement someone at work swore by — text your OB before you take any of them.

03The home-setup checklist

This is the part of the checklist that has a hard deadline attached: it needs to be done before you leave for the hospital. The good news is the actual must-haves are few. Almost everything else can be added later.

A rear-facing car seat, installed

You cannot leave the hospital without one. The American Academy of Pediatrics puts it plainly: "First, install a rear-facing car safety seat in the back of your vehicle. (Note that all U.S. hospitals will check to make sure you have one — so this isn't optional.)" Install it a few weeks before your due date, not the morning of. Many fire stations and pediatricians' offices will double-check the install for free.

One thing the AAP explicitly flags for the ride home: no bulky coats or blankets under the harness. "In the car, though, your baby should be dressed in thin, snug layers like a long-sleeved bodysuit and leggings, with the coat and blankets placed OVER the car safety seat straps."

A safe sleep space, set up per AAP guidance

This one is worth getting right the first time. The AAP's safe sleep guide is the standard, and it is short enough to actually follow:

In practice this means one item: a firm, flat, empty bassinet or crib beside your bed. If you're wondering how the AAP-safe setup pairs with real-world newborn wakings, our newborn sleep schedule guide walks through what those first weeks actually look like.

A hospital bag, packed by 36 weeks

You do not need a specialty duffel or a 40-item packing list. Toiletries, a phone charger with a long cord, snacks, a going-home outfit for you and one for the baby, and your ID and insurance card cover the essentials. Our hospital bag guide has the short, no-affiliate version.

The feeding + soothing basics

This is short too: a few onesies, burp cloths, diapers in newborn and size 1, wipes, a couple of swaddles, and — if you plan to bottle-feed at all — one bottle to start with (you can buy more once you know what your baby will take). Whether you're planning to nurse, bottle-feed, or both, our newborn feeding schedule guide covers how often, how much, and what "normal" actually looks like in week one.

04A trimester-by-trimester at-a-glance

If it helps to see the whole thing on one page:

First trimester (weeks 1-13)

  • Start a daily prenatal vitamin with folic acid.
  • Book your first prenatal appointment (usually 8-10 weeks).
  • Clear medications and supplements with your provider.
  • Cut alcohol, high-mercury fish, and the other flagged foods.
  • Tell your workplace when you're ready — no rush.

Second trimester (weeks 14-27)

  • Anatomy scan around 18-22 weeks.
  • Glucose screening at 24-28 weeks.
  • Start thinking about a birth setting and any classes you want.
  • Begin gentle, regular movement if you have not already.
  • Start a baby registry only if you actually want one — none of it is required.

Third trimester (weeks 28-40+)

  • Tdap vaccine between 27-36 weeks.
  • Group B strep swab around 36 weeks.
  • Install and check the car seat by 36 weeks.
  • Pack the hospital bag by 36 weeks.
  • Set up a safe sleep space (bassinet or crib) in your room.
  • Pick a pediatrician and confirm they'll see the baby.
  • Stock up on a few postpartum essentials for you — this part is often forgotten.

One habit that helps more than any product

Sleep whenever you can, especially in the last month. Once the baby is here, the rules of sleep change — our guide to the fourth trimester walks through what the first twelve weeks actually feel like. Going in rested is worth more than any gadget on your registry.

05The short version

A good pregnancy checklist is not long. Show up for your prenatal visits. Take a prenatal vitamin with folic acid. Skip the short list of foods to avoid. Move gently. Install the car seat. Set up a firm, flat, empty bassinet in your room. Pack a bag by 36 weeks. That is 90% of it.

The rest — the swaddles, the wipe warmer, the tenth onesie — you can add as you go. If you want a week-by-week version of this same list that pings you at the right time, our free week-by-week planner puts each item where it belongs in the pregnancy calendar. And if you are already thinking about what happens after the hospital, our newborn basics guide picks up where this one leaves off.

Questions parents actually ask

When should I schedule my first prenatal appointment?

As soon as you have a positive test. Most first visits happen between 8 and 10 weeks, but calling early lets your provider get you on their schedule and answer any urgent questions. MedlinePlus notes the typical rhythm from there: once a month through week 28, twice a month through week 36, then weekly until birth.

How much folic acid do I need during pregnancy?

MedlinePlus lists 600 micrograms per day during pregnancy and says it is hard to hit that from food alone, so a prenatal vitamin containing folic acid is the standard recommendation. Getting enough before and during pregnancy is what helps prevent major birth defects of the baby's brain and spine.

What foods should I actually avoid while pregnant?

The real must-avoid list is short. MedlinePlus flags alcohol (all of it), high-mercury fish like shark, swordfish, and king mackerel, undercooked meats and eggs, unpasteurized dairy and soft cheeses, and raw sprouts or unwashed produce. Caffeine gets a limit rather than a ban — under 200 mg a day, or about one 12-ounce cup of drip coffee.

When do I need to have the car seat installed?

Well before your due date — a few weeks is a reasonable buffer. The AAP is clear that a rear-facing car safety seat in the back of the vehicle is not optional: every U.S. hospital will check for one before letting you leave with the baby. Many local fire stations or pediatricians' offices will inspect your install for free.

What's the single most important thing to get right before baby comes home?

Two things, honestly: a properly installed rear-facing car seat and a safe sleep space that follows AAP guidance — a firm, flat, empty bassinet or crib in your room, baby on their back, nothing else in the space. The AAP notes room sharing (not bed sharing) can lower the risk of SIDS by as much as 50%.

Do I really need a full baby registry?

No. A registry is convenient if people are asking what to buy, but the actual list of required items is short: car seat, safe sleep space, some diapers and wipes, a few onesies and swaddles, and — if you're bottle-feeding — one bottle to start. Anything else you can add once you know what your baby likes.
