The first thing to do after a positive pregnancy test is start taking a prenatal vitamin with at least 400 mcg of folic acid daily, then call to schedule your first prenatal appointment. Everything else, from food adjustments to medication reviews, can happen over the next few days and weeks. Here’s a practical walkthrough of what to prioritize and in what order.
Start a Prenatal Vitamin Right Away
Folic acid is the single most time-sensitive nutrient in early pregnancy. It helps prevent neural tube defects, which affect the brain and spinal cord and develop very early, often before many people even know they’re pregnant. The CDC recommends 400 mcg of folic acid daily for all women who could become pregnant. If you’ve had a previous pregnancy affected by a neural tube defect, the recommendation jumps to 4,000 mcg daily, starting a month before conception and continuing through the first three months.
Most over-the-counter prenatal vitamins contain the right amount of folic acid along with iron, calcium, and DHA. If you’re already taking one, you’re covered. If not, pick one up at any pharmacy. You don’t need a prescription.
Schedule Your First Prenatal Appointment
Call your provider as soon as you get a positive test. Most offices schedule the first visit somewhere between 8 and 12 weeks, though the timing varies by practice. This appointment is thorough. Expect blood draws to check your blood type and Rh status, hemoglobin levels, immunity to rubella and chickenpox, and screening for infections like hepatitis B, syphilis, chlamydia, gonorrhea, and HIV. You’ll also give a urine sample to check for bladder or urinary tract infections.
Depending on how long it’s been, you may get a pelvic exam and Pap test. Your provider will likely discuss genetic screening options as well. Non-invasive prenatal testing (NIPT) is a blood draw that can be done starting at 10 weeks. It screens for Down syndrome, trisomy 18, trisomy 13, and sex chromosome conditions by analyzing small fragments of fetal DNA circulating in your blood. It takes about 10 weeks of pregnancy for enough of that DNA to be detectable, which is why there’s a minimum gestational age for the test.
Choosing Between an OB-GYN and a Midwife
If you don’t already have a provider, you’ll need to pick one. The two main options are an OB-GYN (obstetrician-gynecologist) and a certified nurse midwife, and they differ in training and approach. OB-GYNs are physicians trained to manage all pregnancies, including high-risk ones, and can perform surgeries like cesarean sections. Midwives are trained to view pregnancy through the lens of what’s normal and to recognize when things move beyond that scope. They tend to spend more time on patient education and hands-on support, and they’re often trained in a wider range of non-medical pain management options.
Certified nurse midwives working in hospitals and medical centers have formal education in gynecological and pregnancy care. They handle prenatal visits, vaginal deliveries, and routine gynecological care like Pap smears, breast exams, and birth control management. They generally care for people with low-to-moderate risk pregnancies and collaborate with OB-GYNs when complications arise. If you have a pre-existing condition like diabetes, high blood pressure, or a history of pregnancy complications, an OB-GYN is typically the better fit from the start.
Review Your Medications
Some common medications are not safe during pregnancy, and the risk can change by trimester. NSAIDs like ibuprofen and naproxen are particularly risky in the third trimester. Certain anti-anxiety and sleep medications are contraindicated throughout pregnancy. Some antifungal medications carry higher risk in the first trimester specifically.
Don’t stop any prescribed medication abruptly, but do call your prescribing provider within the first few days of your positive test to discuss what’s safe to continue. Acetaminophen (Tylenol) is generally considered the safest over-the-counter pain reliever during pregnancy, but even that conversation is worth having at your first prenatal visit. Bring a full list of everything you take, including supplements and herbal products.
Food and Drink Adjustments
Seafood is actually recommended during pregnancy for its omega-3 fatty acids, but type and quantity matter. The Dietary Guidelines for Americans recommend 8 to 12 ounces per week (two to three servings) of low-mercury fish. The FDA specifically warns against eating bigeye tuna, king mackerel, marlin, orange roughy, swordfish, shark, and tilefish during pregnancy because of high mercury levels. Mercury can cross the placenta and accumulate in the fetus at concentrations even higher than your own.
Raw and undercooked seafood is off the table entirely. That includes sushi, sashimi, ceviche, raw oysters, and refrigerated smoked seafood labeled as lox, nova style, or kippered. The concern is bacterial contamination, particularly listeria, which can cause serious complications in pregnancy even when it causes only mild symptoms in the mother.
Caffeine doesn’t need to disappear from your life, but it should come down. Less than 200 mg per day does not appear to be a major contributing factor to miscarriage or preterm birth, according to the American College of Obstetricians and Gynecologists. That’s roughly one 12-ounce cup of coffee, though the exact amount varies by brew method and brand. Keep in mind that tea, soda, chocolate, and some medications also contain caffeine, so it adds up.
Alcohol, Smoking, and Substance Use
No amount of alcohol has been established as safe during pregnancy. Alcohol crosses the placenta freely, and the developing brain is vulnerable throughout all three trimesters. If you were drinking before you knew you were pregnant, that’s extremely common and not a reason to panic, but stopping now is what matters.
Smoking increases the risk of preterm birth, low birth weight, and placental complications. If you smoke, your prenatal provider can connect you with cessation support. The same goes for cannabis and other recreational substances, none of which have an established safe level during pregnancy.
Reducing Environmental Exposures
Chemicals in your environment can cross the placenta, and in some cases, they accumulate in the fetus at higher concentrations than in your own body. The exposures worth paying attention to range from population-level concerns like air pollution and water contamination to everyday individual exposures like personal care products, food packaging, and household pesticides.
Practical steps include switching to fragrance-free cleaning products when possible, wearing gloves when using chemical cleaners, ensuring good ventilation during any cleaning or painting, and avoiding direct contact with pesticides. If your home has old paint, be cautious about lead exposure during any renovation. You don’t need to overhaul your entire life, but reducing the exposures you can control is reasonable.
Your Rights at Work
The Pregnant Workers Fairness Act requires covered employers to provide reasonable accommodations for limitations related to pregnancy, childbirth, or related medical conditions. This means your employer cannot force you to take leave if another accommodation would work, cannot deny you job opportunities because accommodating you would be inconvenient, and cannot retaliate against you for requesting an accommodation.
Reasonable accommodations might include more frequent bathroom breaks, a modified schedule for morning sickness, temporary reassignment away from heavy lifting or chemical exposure, or a place to sit during shifts that normally require standing. The law applies whether or not your condition meets the formal definition of a disability. If your limitation is temporary and you can perform your essential job functions with or without accommodation, you’re covered. You don’t need to disclose your pregnancy to coworkers, but you do need to communicate the limitation to your employer to trigger the accommodation process.
Warning Signs That Need Immediate Attention
Most early pregnancies progress without emergencies, but certain symptoms require urgent medical evaluation. An ectopic pregnancy, where the embryo implants outside the uterus (usually in a fallopian tube), affects roughly 1 in 50 pregnancies. The first warning signs are typically light vaginal bleeding paired with pelvic pain. If the ectopic pregnancy advances, you may feel shoulder pain or a sudden urge to have a bowel movement, both caused by internal bleeding irritating nearby tissues.
Seek emergency care for severe abdominal or pelvic pain with vaginal bleeding, extreme lightheadedness or fainting, or unexplained shoulder pain. A ruptured ectopic pregnancy can cause life-threatening blood loss quickly. Heavy bleeding with or without cramping can also signal a miscarriage and warrants a call to your provider, even if it turns out to be something less serious. Knowing these signs isn’t meant to make you anxious. It’s meant to ensure you act fast in the rare event something is wrong.
