What Week Do Pregnancy Symptoms Start?

Your Guide to the First Signs of Pregnancy

Wondering when pregnancy symptoms actually begin? You’re not alone. Whether you’re actively trying to conceive or just keeping an eye on your body, understanding the timeline of early pregnancy symptoms can offer clarity and peace of mind.

At Nova Women’s Health, we’re here to guide you through every step of your pregnancy journey — starting with those very first signs.

Weeks 1–2: You’re Not Technically Pregnant (Yet)

That’s right! During the first two weeks of pregnancy, your body is preparing for ovulation and fertilization — but pregnancy hasn’t technically started yet.

You may still be having your period or just finishing it.
No real pregnancy symptoms appear during this time.

Keyword tip: early signs of pregnancy aren’t expected this early.

Week 3: Conception Occurs

By week 3, fertilization may have occurred — the egg meets sperm and implants into the uterus.

You might notice subtle signs such as:

Mild cramping
Light spotting (implantation bleeding)

However, for most women, week 3 pregnancy symptoms are minimal or nonexistent.

Week 4: Early Pregnancy Symptoms Begin

Week 4 is often when people first suspect they might be pregnant, especially if their period is late.

Common early pregnancy symptoms at 4 weeks include:

Fatigue
Tender, swollen breasts
Mild nausea or queasiness
Bloating
Increased urination

This is also when home pregnancy tests may show a positive result thanks to rising hCG levels.

Weeks 5–6: Symptoms Ramp Up

As hormone levels rise, so do the symptoms. This is when many women start to really feel pregnant.

What to expect:

Morning sickness (not just in the morning!)
Mood swings
Food cravings or strong aversions
Heightened sense of smell
Sore, enlarging breasts

If you’re asking, “How soon do pregnancy symptoms start?” — weeks 5–6 are typically when things kick into full gear.

Week 7 and Beyond: Things Get Real

Symptoms can intensify around this time, and your body continues to adjust to pregnancy.

You might experience:

Stronger nausea or vomiting
Emotional highs and lows
Breast growth and tenderness
Feeling pregnant even before you’re visibly showing

Every Pregnancy Is Different

Don’t worry if you’re not feeling all (or any) symptoms right away. Some women notice signs as early as week 4, while others may not feel anything until later in the first trimester — or not at all.

If you’re ever unsure, it’s always best to consult with a provider. At Nova Women’s Health, we offer compassionate, expert care from preconception through delivery.
