The first thing to do when you find out you’re pregnant is start a prenatal vitamin (if you’re not already taking one), call to schedule a prenatal appointment, and cut out alcohol. Everything else can be figured out over the coming days and weeks. Here’s a practical walkthrough of the steps that matter most in early pregnancy, roughly in order of priority.
Start a Prenatal Vitamin Right Away
Folic acid is the single most time-sensitive nutrient in early pregnancy. Taking 400 to 800 micrograms daily reduces the risk of neural tube defects, which are serious problems with the baby’s brain and spine that develop in the first few weeks, sometimes before you even know you’re pregnant. Most prenatal vitamins contain this amount. If you’ve been taking one while trying to conceive, you’re already covered.
Beyond folic acid, look for a prenatal that includes at least 300 mg of DHA (an omega-3 fat important for the baby’s brain development), 220 mcg of iodine, and 27 mg of iron. Not every prenatal vitamin includes DHA, so check the label. If yours doesn’t, a separate DHA supplement can fill the gap. Prenatal vitamins are available over the counter at any pharmacy, and you don’t need a prescription to start.
Schedule Your First Prenatal Appointment
Call your provider as soon as you get a positive test. Most offices will schedule your first visit somewhere between 8 and 12 weeks of pregnancy, though some see you earlier depending on your health history. That first appointment is a long one, so expect to set aside extra time.
Your provider will go through your full medical history: past pregnancies, medications you take (including supplements and over-the-counter products), family health history, and lifestyle factors like tobacco, alcohol, or drug use. Be honest about everything, even topics that feel uncomfortable. This information shapes decisions about your care for the entire pregnancy.
You’ll also have blood drawn. These tests check your blood type and Rh factor (a protein on red blood cells that can cause complications if your status doesn’t match the baby’s), your immunity to infections like rubella and chickenpox, and screen for hepatitis B, syphilis, HIV, and other infections. A urine sample checks for urinary tract infections. Your provider will likely offer genetic screening tests, which may include an ultrasound or additional blood work to assess the baby’s risk for conditions like Down syndrome.
Choose Your Prenatal Care Provider
You have several options, and picking the right fit matters more than most people realize. The main choices are an obstetrician (OB), a certified nurse midwife (CNM), or a family physician who practices obstetrics.
Obstetricians are medical doctors and surgeons with at least 12 years of training beyond high school. They’re specifically trained to diagnose and manage complications, and they can perform cesarean sections. If you have a high-risk pregnancy or a chronic health condition, an OB is typically the best choice.
Certified nurse midwives hold graduate degrees in nursing or midwifery and are trained to view pregnancy through the lens of what’s normal, stepping in with referrals when things move beyond that scope. They often spend more time on patient education and hands-on support, and they tend to offer a broader range of non-medical pain management options during labor. CNMs practice in hospitals, birthing centers, and some home settings. If you’re drawn to a less interventional approach and have a low-risk pregnancy, a midwife may be a good match. Be aware that lay midwives, who lack formal certification, are different from CNMs and aren’t credentialed to practice in hospitals.
There’s no wrong answer here. Some people also switch providers mid-pregnancy if the fit isn’t right.
Foods and Drinks to Avoid
Pregnancy weakens parts of your immune system, making you more vulnerable to foodborne illness. Listeria, a bacteria that can cause miscarriage or stillbirth, is the biggest concern. It thrives in foods that many people eat without a second thought.
The high-risk list includes:
- Deli meats, hot dogs, and cold cuts unless heated until steaming
- Soft cheeses like queso fresco, brie, camembert, and blue cheese, especially if made from unpasteurized milk
- Raw or undercooked meat, poultry, eggs, and seafood including sushi, sashimi, ceviche, and runny eggs
- Refrigerated smoked seafood labeled as lox, nova-style, or kippered (fine if cooked into a dish)
- High-mercury fish like shark, swordfish, king mackerel, and tilefish
- Raw sprouts such as alfalfa and bean sprouts
- Unpasteurized milk, juice, or cider
- Premade deli salads like potato salad, chicken salad, and egg salad
- Raw dough or batter including cookie dough, which poses a risk from both raw eggs and raw flour
Wash all fresh fruits and vegetables before eating them, and don’t leave cut melon sitting out for more than two hours (one hour if it’s over 90°F).
Caffeine, Alcohol, and Medications
Alcohol should be eliminated entirely. There is no known safe amount during pregnancy.
Caffeine is fine in moderation. Keeping intake under 200 mg per day does not appear to increase the risk of miscarriage or preterm birth. That’s roughly one 12-ounce cup of brewed coffee. Tea, chocolate, and some sodas also contain caffeine, so factor those in if you’re counting.
For medications, the most important thing to know early on is to avoid ibuprofen (Advil, Motrin) and aspirin. Use all medications sparingly during the first 12 weeks. Acetaminophen (Tylenol) is generally considered the safer option for pain or fever, but check with your provider about anything you take regularly, including supplements and herbal products. If you’re on prescription medications for a chronic condition, don’t stop them on your own. Call your provider to discuss what’s safe to continue.
Exercise During Pregnancy
If you were active before pregnancy, you can generally keep doing what you were doing. The current guideline is at least 150 minutes of moderate-intensity aerobic activity per week, spread across several days. That works out to about 30 minutes, five days a week. Walking, swimming, cycling on a stationary bike, and prenatal yoga all count.
If you were doing vigorous exercise before getting pregnant, like running or high-intensity interval training, you can typically continue as long as your pregnancy is uncomplicated. A large review of studies found that aerobic exercise lasting 35 to 90 minutes, three to four times per week, does not increase the risk of preterm birth. Listen to your body, stay hydrated, and avoid activities with a high fall risk or contact sports. Your provider can help you adjust your routine if needed.
Warning Signs That Need Immediate Attention
Some symptoms in early pregnancy are normal, like mild cramping, breast tenderness, and nausea. Others are not. Contact your provider right away, or go to an emergency room, if you experience any of the following:
- Vaginal bleeding heavier than light spotting, especially anything resembling a period
- Severe belly pain that is sharp, stabbing, or cramp-like and doesn’t go away, or that starts suddenly and worsens over time
- Severe chest, shoulder, or back pain
- Fluid leaking from your vagina
These symptoms don’t always mean something is wrong, but they need evaluation quickly. Ectopic pregnancy, in which the embryo implants outside the uterus, is one serious possibility in the first trimester and typically causes sharp pain on one side. Heavy bleeding with clots can signal a miscarriage. In both cases, getting evaluated promptly makes a real difference in outcomes.
Other Practical Steps in the First Few Weeks
Beyond the medical priorities, a few practical things are worth handling early. If you have dental insurance, schedule a cleaning. Pregnancy hormones increase your risk of gum disease, and dental care during pregnancy is both safe and recommended. Let your dentist know you’re pregnant so they can skip X-rays unless urgent.
Think about who you want to tell and when. Many people wait until after the first trimester, when the risk of miscarriage drops significantly, but there’s no rule. Some people share the news early so they have support if complications arise. This is entirely personal.
If your workplace involves chemical exposure, heavy lifting, prolonged standing, or other physical demands, start thinking about accommodations you may need. In the U.S., the Pregnant Workers Fairness Act requires most employers to provide reasonable accommodations for pregnancy-related needs.
