Pregnancy symptoms

There is no exact number that applies to all women. It depends on the timing of ovulation, cycle length, when fertilization occurred and each body's hormonal response. Some women notice changes before a missed period; many others feel nothing until week five or six, and some almost nothing through the first trimester.

Doctors count from the first day of your last period, not from intercourse or fertilization. In a 28-day cycle, the first two weeks of the medical count happen before conception; by the time your period is late, you are already at about four weeks. Logging your dates in the Boy or Girl ovulation calendar avoids confusion.

They are very hard to identify. Fertilization does not always happen the same day as intercourse (sperm can wait several days for ovulation), and other processes must occur before a test can detect the pregnancy hormone. Nausea, cramps or tiredness one, two or three days later cannot be reliably attributed to pregnancy.

Seven days after intercourse is usually too early to tell a pregnancy apart from normal cycle changes. Mild cramps, breast tenderness, fatigue, bloating or headache at that point may be due to ovulation, progesterone or an approaching period. It also matters whether you count 7 days from intercourse, from ovulation or from a missed period.

In the medical count, "week 1" starts on the first day of your last period, before ovulation or conception has happened; that is why many online answers seem contradictory. In the days after possible fertilization there is no set of symptoms that confirms a pregnancy that early, and having no symptoms is completely normal.

Many women identify them around week four, five or six. A missed period usually shows up around week four in regular cycles; according to ACOG, nausea generally begins before week nine. Symptom intensity does not indicate whether the pregnancy is progressing well.

It is possible, but they are nonspecific: breast tenderness, fatigue, mild cramps, bloating, sensitivity to smells, appetite changes, emotional shifts or mild nausea. All of them also occur with PMS. Before a missed period, a test can be negative even if you are pregnant if there is not yet enough hCG in your urine.

It is too early to attribute those changes to pregnancy. They could be related to ovulation, your period, diet, stress or other causes.

No. In regular cycles it is one of the first signs that raises suspicion, but it can also be caused by stress, weight changes, intense exercise, travel or poor sleep, polycystic ovary syndrome, hormonal changes, some medications, breastfeeding or perimenopause. If you don't remember when your period was due, log your dates in the ovulation calendar.

It can be: hormonal changes make breasts feel tender, swollen, heavy or sore, and some women notice darker areolas or more visible veins. But it is also common before a period. One possible difference is that in pregnancy the tenderness continues past the date your period was due.

Feeling exhausted after sleeping well can be one of the first symptoms, due to hormonal and metabolic changes in the early weeks. It can also be caused by anemia, thyroid issues, infections, stress or lack of sleep. If it is severe, comes with shortness of breath or seriously affects your day, see a professional.

Although called "morning sickness," it can strike at any time of day. According to ACOG, it generally begins before nine weeks. Some women feel only mild queasiness; others vomit frequently. Not having nausea is normal and does not indicate a problem. If vomiting prevents you from keeping fluids down, causes dizziness or greatly reduces urination, you need medical evaluation.

Yes. Blood volume increases, the kidneys process more fluid and bathroom trips become more frequent; it can start in the first weeks. If it comes with burning, pain, fever, pelvic pressure, strong odor or blood in the urine, it may be a urinary tract infection: see a doctor.

Some women develop an aversion to strong smells (perfume, coffee, certain foods), which can trigger nausea and appetite changes. A metallic taste in the mouth may also appear, though not in every pregnant woman.

Mild cramps can occur in the first weeks and feel very much like pre-period discomfort: gentle pressure, pulling or intermittent aches in the lower abdomen. They should not be intense or get worse. Strong, persistent or one-sided pain needs medical evaluation, especially with bleeding, weakness, dizziness or shoulder pain.

Some women have light spotting (a few pinkish, brownish or reddish drops, lighter than a period). Online it is often called "implantation bleeding," but not all early spotting has that cause: it can also relate to cervical changes, infections, early pregnancy loss or ectopic pregnancy. Do not self-diagnose by color or amount. With a positive test and bleeding, tell your OB-GYN; seek urgent care if it is heavy, increases, or comes with severe pain, fainting or weakness.

Hormonal changes slow digestion and can cause bloating, gas, constipation, heaviness or heartburn. But these also happen before a period or with dietary changes; on their own they do not confirm pregnancy.

In the first weeks some women feel hungrier while others temporarily lose their appetite; cravings or aversions to usual foods may appear. Cravings are not proof of pregnancy and do not reveal the baby's sex.

Hormonal changes, tiredness and uncertainty can increase sensitivity, irritability, worry or tearfulness. These emotions also appear with PMS or with the stress of waiting for a test result.

By symptoms alone it can be practically impossible. Rough (non-diagnostic) differences:

• Breasts: in pregnancy tenderness may continue after the missed period; with PMS it eases once the period starts.
• Cramps: mild and intermittent vs. increasing before or during the period.
• Fatigue, bloating and mood: may last weeks vs. improve after the period.
• Nausea: more common in early pregnancy.
• Missed period: an important sign vs. the period eventually arrives.
• Spotting: light vs. develops into a normal menstrual flow.

Bleeding in the first weeks is possible, but period-like bleeding can also have other causes. Take a test and see a professional, especially if it is heavy or painful.

Symptoms are not enough. The most reliable process:

• Identify the date your period was due.
• Take a pregnancy test following the instructions exactly.
• If negative and your period doesn't come, repeat it a few days later.
• See a professional if it is positive or the delay continues.

Home tests detect the hormone hCG in urine; taken too early, they can give a false negative.

From the day your period was due or later, to reduce the risk of a false negative. Tips: follow the manufacturer's instructions, check the expiration date, read the result within the stated time, use first-morning urine if testing very early, avoid drinking lots of water right before, and repeat a few days later if it is negative and your period doesn't arrive.

Boy or Girl has its own pregnancy test available on Amazon. Read and follow the package instructions. No home test replaces evaluation by a healthcare professional.

It may mean there is no pregnancy, but also that it was taken too early, ovulation happened later than expected, urine was very diluted, instructions weren't followed, or the test was expired or damaged. If your period doesn't come, repeat it after a few days; if the delay persists, see a doctor.

Not always. Taken too early it can produce a false negative. Repeat the test a few days later if your period doesn't arrive.

• Contact an OB-GYN or other prenatal care professional.
• Write down the first day of your last period.
• Prepare a list of medications, vitamins and supplements you use; don't stop prescriptions without asking.
• Avoid alcohol, tobacco and drugs.
• Ask about folic acid or prenatal vitamins.
• Seek urgent care for heavy bleeding, severe pain or fainting.

Continue with the Boy or Girl guide on tests after confirming pregnancy, or book an online consultation with Dr. Arnaldo Ojeda.

Track your cycles so you try on the right fertile days: the Boy or Girl Achieve Your Pregnancy app helps you follow your ovulation and prepare for appointments. If you have been trying for 12 months (or 6 if you are 35 or older), see a gynecologist.

Immediately if you have:

• Severe abdominal or pelvic pain, or pain on one side.
• Heavy bleeding.
• Shoulder pain together with abdominal pain or bleeding.
• Severe dizziness, sudden weakness or fainting.
• Fever.
• Persistent vomiting that prevents keeping fluids down.
• Shortness of breath or rapidly worsening pain.

In the United States, call 911 or go to the emergency room.

One-sided pain, bleeding, shoulder pain, dizziness or fainting can occur in an ectopic pregnancy, which can cause internal bleeding and requires urgent care. Don't wait for it to pass: go to the emergency room.
