Finding out you’re pregnant sets off a mental checklist that can feel overwhelming, but the first few weeks are simpler than you might expect. The most important early steps are scheduling a prenatal appointment, starting a prenatal vitamin with folic acid if you haven’t already, and making a handful of straightforward changes to what you eat, drink, and do around the house. Here’s a practical walkthrough of each one.
Start a Prenatal Vitamin Right Away
If you aren’t already taking one, start a prenatal vitamin the day you see a positive test. The most critical ingredient is folic acid. The CDC recommends 400 micrograms daily, and most prenatal vitamins contain 400 to 800 micrograms. Folic acid helps prevent neural tube defects, which are serious problems with the brain and spine that develop very early in pregnancy, often before you even know you’re pregnant. This is specifically folic acid, the synthetic form found in supplements. Other forms of folate haven’t been shown to offer the same protection.
Schedule Your First Prenatal Appointment
Call your OB-GYN, midwife, or family doctor as soon as you get a positive test. Many offices schedule the first visit around 8 weeks, though the timing varies by practice. This appointment is longer than most that follow because it covers a lot of ground: a physical exam, a pelvic exam, possibly a Pap test, and a panel of blood work.
The blood tests check your blood type and Rh status, your iron levels, and your immunity to infections like rubella and chickenpox. You’ll also be screened for hepatitis B, syphilis, gonorrhea, chlamydia, and HIV. A urine sample checks for bladder or urinary tract infections. Your provider will likely discuss genetic screening options, which can include blood tests or ultrasound to check for conditions like Down syndrome. Bring a list of every medication and supplement you currently take, plus any questions you’ve been collecting since you saw that positive test.
Foods and Drinks to Cut or Limit
A few dietary changes reduce the risk of foodborne infections that are especially dangerous during pregnancy. The biggest concern is listeria, a type of bacteria that can cause miscarriage, stillbirth, or premature delivery. To avoid it:
- Deli meats and hot dogs unless reheated until steaming hot.
- Soft cheeses like queso fresco, queso blanco, and any cheese made from unpasteurized (raw) milk.
- Refrigerated smoked seafood labeled as lox, nova-style, kippered, or smoked, unless cooked into a dish like a casserole.
- Refrigerated pâtés or meat spreads.
- Unpasteurized milk or any food made with it.
For caffeine, the guideline from the American College of Obstetricians and Gynecologists (ACOG) is to stay under 200 milligrams a day. That’s roughly one 12-ounce cup of coffee. Going over that amount has been linked to higher risk of miscarriage and preterm birth, though moderate intake below that threshold doesn’t appear to be a significant factor.
Alcohol has no known safe amount during pregnancy, so the standard recommendation is to avoid it entirely.
Medications: What’s Safe and What’s Not
Pregnancy changes which over-the-counter medications you can reach for. The short version: acetaminophen (Tylenol) is considered safe for headaches and pain when used at the lowest dose that works. Ibuprofen, naproxen, and other NSAIDs should be avoided in the first trimester and after 20 weeks because they can affect fetal kidney development.
For nausea, vitamin B6, the antihistamine doxylamine, and ginger are all considered safe options in the first trimester. For heartburn, calcium carbonate (Tums) is the preferred antacid. For congestion and allergies, saline nasal rinses and antihistamines like cetirizine (Zyrtec) or loratadine (Claritin) are safe choices, but you should avoid decongestants like pseudoephedrine and phenylephrine in early pregnancy due to an increased risk of birth defects.
If you take any prescription medication, don’t stop it on your own. Call your prescriber to discuss whether to continue, adjust, or switch.
Household and Environmental Precautions
A parasite called toxoplasma, found in cat feces and undercooked meat, can cause serious pregnancy complications. If you have a cat, have someone else handle the litter box. If that’s not possible, wear disposable gloves and wash your hands thoroughly afterward. The litter should be changed daily, before the parasite has time to become infectious.
Other precautions that reduce toxoplasma exposure: cook all meat to safe internal temperatures, wash and peel fruits and vegetables, and wear gloves while gardening, since outdoor soil can harbor the parasite from neighborhood cats.
Exercise During Pregnancy
Exercise is not only safe for most pregnancies, it’s actively encouraged. ACOG recommends at least 150 minutes of moderate-intensity aerobic activity per week, spread across several days rather than crammed into one or two sessions. Walking, swimming, stationary cycling, and prenatal yoga all fit the bill. If you were already doing vigorous exercise before pregnancy, like running or weight training, you can generally continue as long as your pregnancy is uncomplicated.
The old advice about keeping your heart rate below 140 beats per minute is outdated. Current guidelines focus on how you feel rather than a specific number. You should be able to carry on a conversation during exercise. If you’re gasping for words, dial it back. Your provider can help you tailor an exercise plan if you have any medical or obstetric complications.
Understanding Miscarriage Risk
Worrying about miscarriage in the first trimester is almost universal, and it helps to know what the actual numbers look like. Most miscarriage risk is concentrated in the earliest weeks. A study of over 300 women found that once a heartbeat is visible at 6 weeks, the chance of the pregnancy continuing is about 78%. By 8 weeks with a confirmed heartbeat, that number rises to 98%, and by 10 weeks it reaches 99.4%. The risk drops sharply by the end of week 12, which is why many people wait until then to share the news more widely.
Symptoms to watch for that warrant an immediate call to your provider: vaginal bleeding heavier than light spotting, sharp or worsening abdominal pain that doesn’t go away, a fever of 100.4°F or higher, or leaking fluid from the vagina. Light cramping and occasional spotting can be normal in early pregnancy, but anything that feels sudden, severe, or progressively worse deserves prompt attention.
Telling Your Employer
There’s no legal requirement to tell your employer at a specific point in pregnancy, and many people wait until after the first trimester. When you do share the news, know that you have legal protections. The Pregnant Workers Fairness Act requires covered employers to provide reasonable accommodations for limitations related to pregnancy, childbirth, or related conditions. That might mean more frequent breaks, a modified schedule, permission to sit during a standing job, or temporary reassignment of tasks that involve heavy lifting or chemical exposure.
You don’t need to use specific legal language to request an accommodation. Simply explain what limitation you’re experiencing and what adjustment would help. Your employer cannot deny you job opportunities because you need an accommodation, force you to take leave when a different accommodation would let you keep working, or retaliate against you for making a request. In many cases, especially early in pregnancy, a conversation is enough and your employer shouldn’t require medical documentation.
