If you’ve just found out you’re pregnant, the most important first steps are confirming the pregnancy, scheduling a prenatal appointment, and starting a prenatal vitamin with at least 400 micrograms of folic acid. Everything else builds from there. Here’s a practical walkthrough of what to do, what to change, and what to watch for.
Confirming Your Pregnancy
Home pregnancy tests detect a hormone called hCG in your urine and are generally reliable around the time of your first missed period. A blood test at your doctor’s office is more sensitive and can detect pregnancy about a week after conception. If your home test is positive, that’s typically enough to move forward with scheduling your first prenatal visit. False positives are rare.
If your test is negative but your period still hasn’t arrived, wait a few days and test again. Testing too early is the most common reason for a false negative.
Scheduling Your First Prenatal Visit
Call your doctor or midwife as soon as you have a positive test. Your first prenatal appointment usually happens between weeks 8 and 12, and during your first trimester you’ll have a visit about once a month.
That first visit is thorough. Expect blood draws, a pelvic exam, and a panel of screening tests that check for things like your blood type, immunity to certain infections, hepatitis, and HIV status. You’ll also give a urine sample. Your provider will ask about your health history, past pregnancies, any medications or supplements you take, and whether conditions like genetic disorders run in your or your partner’s family.
This appointment is also your chance to ask questions. Good topics to bring up include how to manage morning sickness, what to expect at future visits, safe exercise, and what to do if you notice vaginal bleeding early on. If you aren’t already taking a prenatal vitamin, you’ll be given one at this visit.
Start a Prenatal Vitamin Now
Don’t wait for your first appointment. The CDC recommends 400 micrograms of folic acid daily for all women who could become pregnant. Folic acid is critical in the earliest weeks of pregnancy because it helps prevent neural tube defects, which are serious problems with the brain and spine that develop before many people even know they’re pregnant. If you’ve had a previous pregnancy affected by a neural tube defect, the recommended dose jumps to 4,000 micrograms daily, which your provider can help you with.
Most over-the-counter prenatal vitamins contain the right amount of folic acid along with iron and other nutrients. Pick one up at any pharmacy.
Foods to Avoid
Certain foods carry bacteria or toxins that pose real risks during pregnancy. The main ones to cut out:
- High-mercury fish: swordfish, shark, king mackerel, marlin, bigeye tuna, orange roughy, and tilefish. Lower-mercury options like salmon, shrimp, and canned light tuna are fine in moderation.
- Unpasteurized dairy and juice: skip soft cheeses like brie, feta, and blue cheese unless the label specifically says “pasteurized.” Same goes for unpasteurized cider or juice.
- Deli meats and hot dogs: these can harbor listeria, a bacteria that causes a rare but serious infection during pregnancy. If you eat them, heat them until steaming hot first.
- Raw or undercooked meat, eggs, and seafood: cook everything thoroughly to reduce the risk of foodborne illness.
Caffeine, Alcohol, and Smoking
You don’t have to give up coffee entirely. Both the American College of Obstetricians and Gynecologists and the American Pregnancy Organization recommend keeping caffeine under 200 milligrams per day. That’s roughly one 12-ounce cup of brewed coffee. Tea, chocolate, and some sodas also contain caffeine, so factor those in.
Alcohol is different. No amount has been proven safe during pregnancy, so the standard guidance is to avoid it completely. The same applies to smoking and recreational drugs. If quitting feels difficult, bring it up at your prenatal visit so your provider can connect you with support.
Medications to Be Careful With
Acetaminophen (Tylenol) is the go-to pain reliever during pregnancy and is considered safe in any trimester. About 65% of pregnant women use it at some point.
For allergies, common antihistamines like loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra) do not appear to increase risk to the baby. For colds, saline nasal sprays are always safe. Cough suppressants containing dextromethorphan also appear safe, but decongestants should be used sparingly, especially during the first trimester.
The bigger concern is what to stop taking. If you’re on any prescription medications, herbal supplements, or high-dose vitamins, mention them at your first visit before making changes on your own. Some medications are unsafe in pregnancy, but stopping others abruptly can also cause problems.
Exercise During Pregnancy
Staying active is one of the best things you can do. The current recommendation is at least 150 minutes of moderate-intensity aerobic activity per week, which works out to about 30 minutes on most days. Walking, swimming, stationary cycling, and prenatal yoga all count.
If you were already doing vigorous workouts before pregnancy, you can generally continue them. A study found that women who started cycling at least 30 minutes three times a week in their first trimester significantly reduced their risk of gestational diabetes. The key is listening to your body: stay hydrated, avoid overheating, and skip activities with a high fall risk or contact sports.
Prenatal Screening and Scans
Throughout pregnancy, you’ll be offered several screening tests. In the first trimester, your provider may discuss options for genetic screening, which can assess the likelihood of certain chromosomal conditions. Between 18 and 22 weeks, you’ll have a detailed ultrasound (sometimes called the anatomy scan) that checks your baby’s organs, limbs, and overall development. This is also when many people learn the sex of the baby, if they want to know.
These screenings are optional, and your provider will walk you through what each one looks for and what the results could mean. It helps to think about what information you’d want before the appointments come up.
Warning Signs That Need Immediate Attention
Most pregnancies progress without emergencies, but knowing what to watch for matters. The CDC identifies several symptoms that require immediate medical care:
- Heavy bleeding or severe belly pain: sharp, stabbing, or cramp-like pain that doesn’t go away, or pain that starts suddenly and worsens.
- A headache that won’t resolve: especially one that comes on suddenly with severe intensity, throbs on one side, or comes with blurred vision.
- Vision changes: flashes of light, blind spots, or sudden blurriness.
- Extreme swelling of the hands or face: swelling so significant that you can’t bend your fingers or your eyes look puffy. This can signal dangerously high blood pressure.
- Fever of 100.4°F or higher.
- Severe nausea and vomiting: if you can’t keep fluids down for more than 8 hours or food for more than 24 hours.
- Trouble breathing or chest pain: tightness, pressure, or a fast or irregular heartbeat.
- Fainting or ongoing dizziness.
- Baby’s movement slowing or stopping: this applies later in pregnancy when you’ve been tracking kicks.
- Thoughts of harming yourself or your baby: feelings of hopelessness, extreme anxiety, or intrusive scary thoughts. These are medical symptoms, not personal failings, and treatment helps.
If any of these come up, don’t wait for your next scheduled appointment. Call your provider or go to the emergency room.
The Emotional Side
Finding out you’re pregnant can bring excitement, anxiety, overwhelm, or all of these at once. Hormonal shifts in the first trimester are intense, and feeling more tired, emotional, or foggy than usual is completely normal. So is feeling ambivalent, even if the pregnancy was planned.
Build support early. That might mean telling a partner, a close friend, or a family member, or it might mean finding an online community if you’re not ready to share widely. If anxiety or low mood starts interfering with your daily life, bring it up with your provider. Perinatal mood disorders are common, treatable, and not something you need to push through alone.
