Your first trimester: what to expect (weeks 1–12)

Key facts

What happens in the first trimester

This is when your baby's major organs begin to form — a lot is happening even though there's little to see on the outside. Your body is adjusting to new hormones, which is why you may feel tired or queasy well before you 'show'.

Common early symptoms

Every pregnancy is different, but the usual early signs include:

What to do now

A few simple steps make a real difference in these early weeks:

Your first prenatal visit

The first visit is mostly a conversation — your history, your dates and any concerns. It usually includes an early (dating) scan to confirm the pregnancy and your due date, and some routine blood tests. You'll leave with a clear plan for the months ahead.

Warning signs — when to call

Most early pregnancies are healthy, but call your doctor promptly if you have:

A gentle note

It's normal to feel a mix of excitement and worry in these first weeks. You don't need to have everything figured out — that's exactly what your prenatal visits are for.

Have a question about this?

The clearest next step is a calm consultation. Dr. Ritika will talk it through with you — no rush, no jargon.

Questions, answered

When should I see a doctor after a positive test?

Around weeks 6–8 is usual, but book earlier if you have bleeding, pain, or a medical condition that needs review.

Is light spotting normal in early pregnancy?

Light spotting can be harmless and is fairly common, but any bleeding is worth mentioning to your doctor — and heavy bleeding should be checked straight away.

Is morning sickness a good sign?

Nausea is very common and not a cause for worry in itself. Its absence isn't a bad sign either — every pregnancy is different.

What should I avoid in the first trimester?

Alcohol, smoking, raw or undercooked foods, and any medicine not cleared by your doctor. When in doubt, ask.

When is the first scan?

Usually a dating scan around weeks 6–9, which confirms the pregnancy and estimates your due date.
