The first thing to do when you find out you’re pregnant is start taking a prenatal vitamin with folic acid, then schedule a prenatal appointment for before 10 weeks of gestation. Everything else, from adjusting your diet to knowing which symptoms are normal, builds from those two steps. Here’s a practical walkthrough of what matters most in these early weeks.
Schedule Your First Prenatal Visit
Call your OB-GYN, midwife, or family doctor to book your first prenatal appointment. Current guidelines recommend this comprehensive visit happen before 10 weeks of gestation, so don’t wait. If you don’t have a provider yet, ask your insurance plan for a list of in-network maternity care professionals, or contact a local health department for options.
At this visit, your provider will confirm the pregnancy, estimate your due date, and run a panel of blood tests. These typically include a complete blood count to check for anemia, your blood type and Rh factor, immunity to rubella, hepatitis B screening, HIV testing, and STI screenings for chlamydia and syphilis. You’ll also discuss your medical history, current medications, and any social or environmental factors that could affect your pregnancy. Think of this appointment as a full intake: bring a list of every medication, supplement, and vitamin you currently take.
Estimate Your Due Date
Your provider will confirm this with an ultrasound, but you can get a rough estimate on your own using Naegele’s Rule. Take the first day of your last menstrual period, count back three calendar months, then add one year and seven days. So if your last period started June 1, you’d count back to March 1 and add a year and seven days, landing on March 8 of the following year. This assumes a 28-day cycle, so it’s an approximation, not a guarantee.
Start a Prenatal Vitamin With Folic Acid
Folic acid is the single most time-sensitive nutrient in early pregnancy. It helps prevent neural tube defects, and the critical window is the first two to three months after conception, often before many people even realize they’re pregnant. The recommended intake during pregnancy is 600 micrograms of dietary folate equivalents per day. The U.S. Preventive Services Task Force recommends 400 to 800 micrograms of folic acid daily from a supplement, ideally starting at least a month before conception.
If you weren’t already taking folic acid before your positive test, start now. A standard over-the-counter prenatal vitamin covers this, plus iron, calcium, and other nutrients your body needs in higher amounts during pregnancy. No prescription is necessary for most prenatal vitamins, so you can pick one up at any pharmacy today.
Adjust What You Eat and Drink
Pregnancy changes your immune system in ways that make you more vulnerable to foodborne illness. Pregnant women are 10 times more likely to develop a Listeria infection than the general population, and Listeria can cause miscarriage, stillbirth, or serious illness in a newborn. The foods that carry the highest risk are straightforward to avoid once you know what they are.
- Deli meats and hot dogs: Skip them unless they’re heated until steaming. This includes cold cuts, fermented sausages, and refrigerated pâté or meat spreads.
- Soft cheeses: Avoid queso fresco, brie, camembert, blue cheese, and similar soft varieties, especially if made from unpasteurized milk. Hard cheeses and pasteurized cottage cheese are fine.
- High-mercury fish: Steer clear of shark, swordfish, king mackerel, and tilefish. Lower-mercury options like salmon, tilapia, and shrimp are safe and actually beneficial.
- Raw or undercooked foods: This means no rare steak, runny eggs, raw sushi, or unpasteurized milk and juice.
- Unwashed produce: Rinse all fruits and vegetables thoroughly, even pre-bagged salads.
Caffeine is worth paying attention to as well. Research has linked consumption above 200 milligrams per day (roughly two standard cups of coffee) to smaller birth size and growth restriction. Some recent NIH-funded research found reductions in infant size even below that 200-milligram threshold, prompting some experts to suggest limiting or skipping caffeine entirely during pregnancy. If you’re a heavy coffee drinker, tapering down in these first weeks is a reasonable step.
Review Your Medications
Before you stop or start anything, talk to your provider. Some medications you’ve been taking casually, like ibuprofen or naproxen, are generally avoided during pregnancy. Even acetaminophen, long considered the safest over-the-counter pain reliever for pregnant women, has come under closer scrutiny: some studies have found associations between chronic use throughout pregnancy and neurological conditions in children, though a direct cause hasn’t been established.
The key principle is that no medication should be assumed safe or unsafe without a conversation. This includes herbal supplements, dietary products, and vitamins beyond your prenatal. Make a complete list of everything you take and bring it to your first appointment.
Keep Moving
Exercise during pregnancy is not only safe for most people, it’s actively recommended. The goal is at least 150 minutes of moderate-intensity aerobic activity per week, spread across several days rather than crammed into one or two sessions. Activities that have been extensively studied and found safe during pregnancy include walking, stationary cycling, swimming, water aerobics, dancing, resistance training with weights or bands, and stretching.
What you should avoid: contact sports or activities with a high risk of abdominal trauma (think kickboxing or basketball), anything with significant fall risk like downhill skiing, and scuba diving, which poses unique risks to fetal circulation. If you were already exercising before pregnancy, you can generally continue your routine with modifications as needed. If you weren’t, walking is a perfect place to start.
Stop Alcohol and Tobacco
There is no established safe amount of alcohol during pregnancy. Alcohol crosses the placenta and can affect fetal development at any stage, but the first trimester is a particularly sensitive period of organ formation. If you were drinking before you knew you were pregnant, don’t panic, but do stop now. The same applies to smoking and vaping, both of which increase the risk of preterm birth, low birth weight, and placental complications. If quitting feels difficult, your prenatal provider can connect you with support programs.
Know Which Symptoms Need Urgent Attention
Some discomfort in early pregnancy is normal: nausea, breast tenderness, fatigue, and light spotting are all common. But certain symptoms warrant immediate medical attention, either by calling your provider or going to an emergency room.
- Heavy vaginal bleeding: Anything more than light spotting, especially if it resembles a period or comes with clots.
- Severe belly pain that doesn’t go away: Particularly if accompanied by back pain, dizziness, or vaginal bleeding, which could signal an ectopic pregnancy.
- Fluid leaking from your vagina: Especially if it’s bloody, greenish, or has a bad smell.
- High fever: Low-grade fevers don’t typically require medication, but persistent or high fevers need evaluation.
- Severe nausea and vomiting: Beyond typical morning sickness, to the point where you can’t keep food or liquids down.
- A headache that won’t go away or gets worse: Especially with vision changes, dizziness, or swelling in your hands and face.
Light cramping on its own is usually the uterus stretching and is not a cause for alarm. But cramping paired with bleeding, or pain that’s sharp and one-sided, is worth a call to your provider right away.
What the First Weeks Actually Feel Like
For many people, early pregnancy feels like a strange limbo. You may have intense symptoms or almost none. Nausea tends to peak between weeks 6 and 9. Fatigue can be overwhelming, the kind where you fall asleep at 8 p.m. without meaning to. Your breasts may feel sore and heavy. You might notice heightened sensitivity to smells or sudden food aversions.
All of this is driven by rapidly rising hormone levels and is a normal part of your body adapting to pregnancy. It doesn’t reflect anything about how the pregnancy is going. Some people with perfectly healthy pregnancies have no morning sickness at all, while others are miserable for weeks. The wide range of “normal” is genuinely wide. Focus on the concrete steps: get your prenatal vitamin, book your appointment, adjust your diet, and reach out to your provider with questions as they come up.
