If you think you might be pregnant, the first step is to take a home pregnancy test on or after the day you expect your period. These tests are 99% accurate when used correctly at that point, and they’re the fastest way to get a clear answer from home. Everything else, from scheduling a provider visit to adjusting what you eat, flows from that result.
Here’s a practical walkthrough of what to do right now and in the days ahead.
Recognize the Early Signs
The earliest pregnancy symptoms overlap heavily with premenstrual symptoms, which is why so many people second-guess what they’re feeling. Breast tenderness, fatigue, mood shifts, and mild cramping can show up in both situations. A few differences are worth paying attention to.
Breast soreness from PMS typically peaks right before your period and then eases once bleeding starts. In early pregnancy, it tends to persist and may feel heavier or more sensitive than your usual premenstrual tenderness. Food cravings also differ: PMS cravings lean toward general categories like chocolate or salty snacks, while pregnancy cravings are often oddly specific, sometimes paired with strong aversions to smells or foods you normally enjoy.
Light spotting can also be an early clue. Implantation bleeding happens when a fertilized egg attaches to the uterine lining, typically 10 to 14 days after ovulation. It looks like pink or light brown spotting, lasts anywhere from a few hours to about two days, and is light enough that you’d notice it on toilet paper or as a small spot in your underwear rather than filling a pad. If the bleeding is bright red, heavy, or contains clots, that’s more consistent with a period.
When and How to Take a Test
Home pregnancy tests detect a hormone called hCG in your urine. Your body starts producing hCG shortly after a fertilized egg implants, but levels are extremely low at first. At 9 days after conception, the average hCG concentration is still under 1 mIU/ml. By day 11, the median jumps to about 25 mIU/ml, which is the threshold most home tests need to give an accurate positive result.
This is why timing matters so much. Most reliable home tests advertise 99% accuracy “from the day of your expected period,” and that claim holds up when tested in clinical settings. Some brands market themselves as detecting pregnancy “8 days early,” but researchers have found those claims inconsistent with how quickly hCG actually rises. Testing too early increases your chance of a false negative, meaning you could be pregnant but get a negative result simply because hCG hasn’t built up enough yet.
For the most reliable result:
- Wait until the day your period is due, or ideally one to two days after, before testing.
- Use your first morning urine, which is the most concentrated.
- Follow the instructions exactly, including the wait time before reading the result.
If you get a negative result but your period still hasn’t arrived after a few more days, test again. If you get a positive result, it’s very likely accurate. False positives are rare.
Blood Tests for Earlier Detection
A blood test at your provider’s office can detect pregnancy slightly earlier, within 7 to 10 days after conception, because it picks up smaller amounts of hCG than a urine test can. A quantitative blood test also measures exactly how much hCG is present, which helps your provider track whether the pregnancy is progressing normally. You don’t need a blood test to confirm a positive home test, but your provider may order one depending on your situation.
Start Folic Acid Right Away
If your test is positive, or even if you’re still waiting to test, start taking 400 micrograms of folic acid daily. This B vitamin plays a critical role in preventing neural tube defects, which are serious birth defects of the brain and spine that develop very early in pregnancy, often before many people even know they’re pregnant. The CDC recommends 400 mcg daily for anyone who could become pregnant. Most prenatal vitamins contain this amount, so picking one up at a pharmacy covers this step.
Adjust What You Eat and Drink
A few dietary changes matter immediately. The biggest risks involve bacteria and mercury.
Skip raw or undercooked fish and shellfish, including sushi, sashimi, ceviche, and raw oysters. Avoid high-mercury fish entirely: swordfish, shark, king mackerel, marlin, orange roughy, bigeye tuna, and tilefish. Mercury can damage a developing nervous system, and these large, long-lived fish accumulate the most.
Cook all meats and poultry thoroughly, and either heat deli meats and hot dogs until steaming or avoid them altogether. These can carry listeria, a bacterium that’s rare in the general population but particularly dangerous during pregnancy. Refrigerated pâtés and meat spreads carry the same risk, though canned or shelf-stable versions are fine. Smoked seafood labeled as lox, nova style, or kippered should also be cooked before eating or skipped entirely.
Alcohol is best eliminated completely once you suspect pregnancy. There is no established safe amount during pregnancy.
Review Your Medications
Take stock of anything you’re currently taking, including over-the-counter pain relievers, supplements, and prescriptions. Some common medications aren’t safe in pregnancy, and others may need dose adjustments. Don’t stop a prescription abruptly on your own, especially for conditions like epilepsy, depression, or high blood pressure, because suddenly stopping can also carry risks. Instead, call your provider as soon as you have a positive test to discuss what to continue, what to pause, and what to switch.
Even acetaminophen, which was long considered the safest pain reliever during pregnancy, has come under closer scrutiny. Some studies have found associations between chronic use throughout pregnancy and neurological conditions in children. Occasional use is still generally considered low risk, but it’s worth being intentional about it rather than reaching for it by default.
Reduce Chemical Exposures at Home
You don’t need to overhaul your entire household, but a few simple swaps lower your exposure to chemicals that can interfere with fetal development. Look for personal care products free of phthalates, parabens, oxybenzone, and triclosan. Choose products labeled “fragrance free” rather than “unscented,” since unscented products can still contain chemical fragrance blends.
For cleaning, vinegar and baking soda handle most everyday jobs, or look for products specifically labeled nontoxic. If you normally have clothes dry cleaned, try to avoid it during pregnancy, as many dry-cleaning processes use toxic solvents. Anyone who works in farming, beauty salons, cleaning services, or health care should talk with their provider about workplace-specific precautions.
Stay Active, but Adjust Intensity
Exercise during pregnancy is safe and beneficial for most people. Current guidelines from the American College of Obstetricians and Gynecologists recommend keeping your heart rate below about 140 beats per minute and exercising at an intensity that feels “fairly light to somewhat hard.” That translates to a pace where you can still hold a conversation. Walking, swimming, prenatal yoga, and light strength training are all solid options. If you were already doing more intense workouts before pregnancy, you can likely continue with modifications, but check with your provider on the specifics.
Schedule Your First Prenatal Visit
Call to schedule a prenatal appointment as soon as you get a positive test. Most providers will see you between 8 and 10 weeks of pregnancy, counting from the first day of your last period. At that visit, you’ll typically have bloodwork, a urine screen, and often an early ultrasound to confirm the pregnancy’s location and estimate a due date. Bring a list of your current medications, any supplements you’re taking, and your best estimate of when your last period started.
If you have a history of ectopic pregnancy, are experiencing sharp one-sided pain, or have heavy bleeding with a positive test, call your provider right away rather than waiting for a routine appointment.
If You’re Unsure About the Pregnancy
Not every positive test comes with clear feelings about what to do next. If you’re weighing your options, you have time to think. Pregnancy options include continuing the pregnancy and parenting, adoption, and abortion. The best support during this decision comes from a provider or counselor trained in nonjudgmental options counseling, where all three paths are discussed with equal care and you aren’t steered toward a particular choice. Your primary care provider, an OB-GYN, or a reproductive health clinic can connect you with this kind of support. Taking a few days to process your feelings before making decisions is completely reasonable.
