The first thing to do when you find out you’re pregnant is schedule a prenatal appointment, ideally before 10 weeks from the start of your last period. From there, pregnancy becomes a series of manageable steps: adjusting your diet, staying active, taking the right supplements, and knowing which warning signs need immediate attention. Here’s a practical walkthrough of what matters most.
Schedule Your First Prenatal Visit
Your initial prenatal assessment should happen before 10 weeks of pregnancy or as soon as possible after you discover you’re pregnant. This visit typically includes blood work, a urine test, a review of your health history, and sometimes an early ultrasound to confirm the pregnancy’s location and estimate your due date.
After that first appointment, the traditional schedule looks like this: visits every four weeks through your seventh month, every two weeks through the eighth month, then weekly until delivery. Your provider may adjust this based on your health and any risk factors. These visits track your blood pressure, weight, the baby’s growth, and give you a regular chance to ask questions or flag new symptoms.
Start Prenatal Supplements Early
Folic acid is the single most time-sensitive nutrient in pregnancy. It helps prevent neural tube defects, which develop in the first few weeks, often before you even know you’re pregnant. The recommended intake during pregnancy is 600 micrograms daily from food and supplements combined. If you weren’t already taking a supplement, start now with 400 to 800 micrograms of folic acid per day.
Iron needs increase significantly during pregnancy. The recommended daily amount jumps to 27 milligrams to support the extra blood volume your body is building. Most prenatal vitamins cover this, but your provider may recommend additional iron if your levels are low. Iodine, which supports your baby’s brain development and thyroid function, is recommended at 220 micrograms per day during pregnancy. Many prenatal vitamins include 150 micrograms of iodine, so check your label.
Foods to Avoid
Certain foods carry bacteria or toxins that are especially dangerous during pregnancy. The main concerns are mercury in fish, a bacterium called listeria in unpasteurized products, and other foodborne pathogens in raw or undercooked foods.
Avoid high-mercury fish entirely: swordfish, shark, king mackerel, marlin, orange roughy, bigeye tuna, and tilefish. Mercury damages a developing nervous system, and bigger, older fish accumulate the most. You can still eat lower-mercury seafood like salmon, shrimp, and canned light tuna, which provide beneficial omega-3 fats.
Skip soft cheeses like brie, feta, and blue cheese unless the label specifically says they’re made with pasteurized milk. Unpasteurized juice and cider carry the same risk. Raw or undercooked seafood (sushi, sashimi, ceviche, smoked salmon labeled “lox” or “nova style”) is off the table, as are raw sprouts of any kind, including alfalfa, clover, and mung bean. Wash all raw fruits and vegetables thoroughly before eating.
No amount of alcohol has been proven safe during pregnancy. Drinking increases the risk of miscarriage, stillbirth, and fetal alcohol syndrome. The safest approach is to avoid it completely.
Caffeine and Other Lifestyle Changes
You don’t need to give up caffeine entirely, but keep it under 200 milligrams per day. That’s roughly one 12-ounce cup of coffee. Tea, chocolate, and some sodas also contain caffeine, so factor those in. At this level, caffeine does not appear to significantly contribute to miscarriage or preterm birth.
If you smoke, stopping is one of the most impactful things you can do for your pregnancy. The same applies to recreational drugs. Talk to your provider about support options if quitting feels difficult.
Staying Active During Pregnancy
Exercise during pregnancy is not just safe, it’s recommended. Aim for at least 150 minutes of moderate-intensity aerobic activity per week, which works out to about 30 minutes on five days. Walking, swimming, stationary cycling, and prenatal yoga all count. Moderate intensity means you can carry on a conversation but would struggle to sing.
After the first trimester, avoid exercises that require lying flat on your back, since the weight of your uterus can compress a major blood vessel and reduce blood flow. Contact sports, activities with a high fall risk (skiing, horseback riding), and hot yoga or hot tubs that raise your core temperature are also worth skipping. If you were active before pregnancy, you can generally continue your routine with modifications. If you’re starting fresh, build up gradually.
How Much Weight to Gain
Weight gain recommendations depend on your pre-pregnancy BMI. For a single baby:
- Underweight (BMI under 18.5): 28 to 40 pounds
- Normal weight (BMI 18.5 to 24.9): 25 to 35 pounds
- Overweight (BMI 25 to 29.9): 15 to 25 pounds
- Obese (BMI 30 to 39.9): 11 to 20 pounds
If you’re carrying twins, the targets are higher. A normal-weight person carrying twins should expect to gain 37 to 54 pounds. Most of this weight isn’t body fat. It’s the baby, placenta, amniotic fluid, increased blood volume, and breast tissue. Weight gain is typically slow in the first trimester (a few pounds total) and picks up to about a pound per week in the second and third trimesters.
Medications and Environmental Hazards
Not all over-the-counter medications are safe during pregnancy. One common example: pseudoephedrine, a decongestant found in many cold medicines, has been linked to a small risk of birth defects when taken in the first trimester. Before taking any medication, including pain relievers, allergy pills, or cold remedies, check with your provider. Some antihistamines and nasal sprays are considered safe, but the specifics depend on the product and your trimester.
Lead exposure is another concern worth knowing about. Lead stored in your bones from past exposure can be released into your bloodstream during pregnancy, potentially increasing the risk of miscarriage, preterm birth, low birth weight, and developmental problems. If you live in a home built before 1978 (when lead paint was banned), work in an industry with lead exposure, or have other risk factors, ask your provider about a blood lead test. A diet high in iron and calcium can help reduce lead absorption.
Mental Health Matters Too
Pregnancy-related depression and anxiety are more common than many people realize, and they can start during pregnancy, not just after delivery. Your provider should screen you for depression and anxiety at your first prenatal visit, again later in pregnancy, and at your postpartum visits. These screenings are short questionnaires, not lengthy evaluations.
If you’re feeling persistently sad, anxious, overwhelmed, or disconnected, bring it up even if it’s between scheduled screenings. Hormonal changes, physical discomfort, financial stress, and relationship shifts can all compound during pregnancy. Treatment options exist and are effective. Thoughts of harming yourself or your baby are a medical emergency and should be addressed immediately.
Warning Signs That Need Immediate Attention
Most pregnancy symptoms are uncomfortable but normal. A few, however, signal something serious. Get medical help right away if you experience any of the following:
- Vaginal bleeding or fluid leaking
- Severe belly pain that doesn’t go away
- A headache that won’t go away or keeps getting worse
- Changes in your vision (blurriness, seeing spots)
- Extreme swelling of your hands or face
- Chest pain or a fast-beating heart
- Trouble breathing
- Fever
- Severe nausea and vomiting beyond typical morning sickness
- Your baby’s movements slowing or stopping
- Swelling, redness, or pain in one leg
- Dizziness or fainting
If you can’t reach your provider, go to an emergency room. Make sure to tell them you’re pregnant, even if it seems obvious, since it changes which tests and treatments they’ll use.
