A positive home pregnancy test is accurate the vast majority of the time. False positives are rare and typically only happen in specific circumstances, like a very early pregnancy loss, recent use of fertility medication containing hCG, or certain ovarian conditions. So if you’re seeing that second line or a “pregnant” reading, your next steps matter. Here’s what to do, in roughly the order it makes sense to do it.
Confirm the Result
Home pregnancy tests detect hCG, a hormone your body produces after a fertilized egg implants in the uterus. By the time a test reads positive, hCG levels are already climbing fast. At four weeks of pregnancy (around the time of a missed period), levels range from 0 to 750 µ/L. By weeks eight through twelve, they can reach 32,000 to 210,000 µ/L.
If you want extra reassurance, take a second test the following morning using your first urine of the day, which has the highest concentration of hCG. But a single positive result on a modern home test is reliable enough to start acting on. You don’t need to wait for a blood test to begin making changes.
Schedule a Prenatal Appointment
Call an OB-GYN, midwife, or family doctor and schedule your first prenatal visit. This appointment typically happens between eight and twelve weeks of pregnancy, so you have a window, but don’t wait too long. Many offices book out several weeks, and getting on the calendar early ensures you’re seen before the 12-week mark.
When you call, the office will ask for the first day of your last menstrual period. That date is how your provider estimates your due date. The standard formula: take the first day of your last period, count back three calendar months, then add one year and seven days. That gives you a rough due date based on a 28-day cycle. Your provider will refine it with an ultrasound at your first visit.
At that appointment, expect blood work, a medical history review, and an early ultrasound to confirm the pregnancy’s location and timing. This is also when your provider will screen for any conditions that need monitoring.
Start a Prenatal Vitamin
If you’re not already taking one, start a prenatal vitamin right away. The most critical ingredient is folic acid. The CDC recommends 400 micrograms (mcg) daily to help prevent neural tube defects, which are serious birth defects of the brain and spine. These defects develop very early, often before many people even know they’re pregnant, so the sooner you start, the better.
Most over-the-counter prenatal vitamins contain the recommended amount. Look for one that includes folic acid, iron, and calcium. If a pill makes you nauseous (common in early pregnancy), gummy versions are easier on the stomach, though they often lack iron, so check the label.
Adjust What You Eat and Drink
A few dietary changes reduce real risks during pregnancy. The biggest concern is listeria, a bacteria that can cause serious complications. To lower your exposure:
- Avoid deli meats, hot dogs, and luncheon meats unless you heat them until steaming hot.
- Skip unpasteurized milk and cheeses made from raw milk, including soft cheeses like queso fresco, queso blanco, and requesón (these carry risk even when made from pasteurized milk).
- Skip refrigerated smoked seafood (labeled as lox, nova-style, kippered, or smoked) unless it’s cooked into a dish like a casserole.
- Avoid refrigerated pâtés and meat spreads.
High-mercury fish like swordfish, shark, king mackerel, and tilefish should also be off the menu. Lower-mercury options like salmon, shrimp, and tilapia are safe in moderate amounts and provide beneficial omega-3 fatty acids.
Stop Alcohol and Limit Caffeine
There is no established safe amount of alcohol during pregnancy. Stop drinking as soon as you get a positive test. If you had a few drinks before you knew, don’t panic. The risk increases with regular or heavy consumption, and your provider can address any concerns at your first visit.
Caffeine doesn’t need to disappear entirely, but keep it under 200 mg per day. That’s roughly two standard cups of brewed coffee. Tea, soda, and chocolate also contribute to your daily total, so factor those in. Most people find this limit manageable once they’re aware of it.
Review Your Medications
Some common over-the-counter medications are not safe during pregnancy. The most important ones to stop immediately are ibuprofen (sold as Advil or Motrin) and aspirin. For headaches or general pain, acetaminophen (Tylenol) is the standard alternative considered safe during pregnancy.
If you take any prescription medications, don’t stop them on your own. Call your prescribing doctor or your new prenatal provider and ask about safety during pregnancy. Some medications need to be tapered, switched, or continued because the condition they treat poses a greater risk than the medication itself. This is especially true for medications managing seizures, blood pressure, thyroid conditions, or mental health.
Know the Warning Signs
Most early pregnancies progress normally, but certain symptoms need immediate medical attention. An ectopic pregnancy, where the embryo implants outside the uterus (usually in a fallopian tube), is a medical emergency. Early signs include light vaginal bleeding combined with pelvic pain, often on one side. If the tube ruptures, symptoms escalate to severe abdominal pain, shoulder pain, extreme lightheadedness, or fainting. These require an emergency room visit, not a phone call to your doctor’s office.
Some spotting and mild cramping in early pregnancy is normal and doesn’t automatically mean something is wrong. But heavy bleeding, soaking through a pad in an hour, or severe pain that doesn’t let up warrants a call to your provider or a trip to the ER.
If This Pregnancy Wasn’t Planned
Not every positive test comes with excitement, and that’s a reality many people face. If you’re unsure about continuing the pregnancy, you have three options: parenting, adoption, or termination. The standard of care is nondirective, patient-centered counseling, meaning a provider should give you comprehensive and accurate information about all three paths without pushing you toward any one choice.
Your OB-GYN, a family planning clinic, or a licensed counselor can walk you through what each option involves, including timelines, procedures, and support resources. If you’re considering termination, timing matters, as options and access vary by gestational age and by state. Making an appointment to discuss your options early gives you the most flexibility regardless of what you decide.
Early Lifestyle Habits That Help
Beyond the big-ticket items, a few smaller changes make a difference in the first trimester. Stay hydrated, especially if morning sickness hits. Eat smaller, more frequent meals to manage nausea. Light to moderate exercise is safe and beneficial for most pregnancies, so if you have an existing routine, you can generally continue it. Your provider can offer specific guidance based on your activity level.
Sleep may become harder as symptoms ramp up. Fatigue in the first trimester is intense for many people, driven by the same rapidly rising hCG levels that triggered your positive test. Resting when you can isn’t laziness; your body is doing an enormous amount of work at the cellular level, even before anything is visible from the outside.
