Bleeding in early pregnancy: when should you worry?

By Dr Najib Boudra, obstetrician gynecologist. Updated on 9 November 2026.

You are a few weeks pregnant, everything seemed fine, and this morning you notice blood. Your heart races and questions pile up. Is it serious? Should you go to the emergency department or wait? Many women go through this moment, and it deserves a clear answer rather than a panicked search online.

Bleeding in early pregnancy does not always mean something is wrong. But it should never be ignored. Here, Dr Najib Boudra explains the possible causes, the signs that call for an urgent visit and what is checked during a pregnancy follow-up consultation in Fes (page in French).

Bleeding in the first trimester: common, but never trivial

Light bleeding is common in the first weeks of pregnancy. The NHS points out that it is often not serious, but it should always be reported to a health professional. The reason is simple: with the naked eye, nothing can tell harmless bleeding apart from bleeding that needs care.

Blood can look different from one woman to another: a few brownish spots on your underwear, pink discharge when you wipe, or brighter red bleeding, sometimes with clots. Write down what you notice. These details help the doctor, but they never replace an examination.

If you have not confirmed your pregnancy yet, our article on when to take a pregnancy test will help you read the result.

Possible causes of early bleeding

Implantation bleeding

Around the time your period was due, the embryo settles into the lining of the uterus. This can cause light pink or brown spotting that is short and scanty. Many women mistake it for a light period.

A more sensitive cervix

During pregnancy, the cervix has a richer blood supply. Intercourse or a gynecological examination can cause light bleeding, which is usually harmless.

An infection

A vaginal or cervical infection can cause blood-stained discharge, sometimes with itching or an unusual smell. It can be treated once it has been identified.

A miscarriage or an ectopic pregnancy

These are the two situations the doctor wants to rule out first. A miscarriage may show as bleeding with cramps. An ectopic pregnancy, which develops outside the uterus, can cause bleeding and pain on one side of the abdomen. Only an ultrasound scan and blood tests can tell.

Warning signs that need care without delay

Some signs should not wait for a routine appointment. Call your doctor or go to the emergency department if you have:

• heavy bleeding that soaks a pad quickly;
• severe pain in the lower abdomen, especially on one side;
• pain at the tip of the shoulder with no clear reason;
• dizziness, feeling faint or fainting;
• fever or chills;
• passing clots or tissue.

These symptoms can point to an ectopic pregnancy or a miscarriage in progress, two situations that need a quick assessment. A trip that turns out to be unnecessary is far better than delayed care.

What happens at the consultation

The appointment starts with precise questions: the date of your last period, how the bleeding looks and how much there is, any pain, your medical history. Then comes the examination.

The ultrasound scan

It checks that the pregnancy is inside the uterus and, depending on how far along you are, shows the embryo’s heartbeat. Very early on, the image may still be too small to conclude, so the doctor may suggest another scan a few days later.

Blood tests

The pregnancy hormone, beta-hCG, is often measured twice, 48 hours apart. The way it changes shows how the pregnancy is progressing. The doctor also checks your blood group and rhesus factor, because a preventive injection may be discussed depending on your situation.

To see where these tests fit in the whole follow-up, read our pregnancy ultrasound calendar.

And later in pregnancy?

Bleeding in the second or third trimester has different causes. It can be linked to the position of the placenta, to the placenta coming away from the wall of the uterus or to changes in the cervix. In every case, the rule is the same: see a doctor the same day, without waiting for it to stop.

If the bleeding comes with contractions, leaking fluid or fewer baby movements, go straight to the maternity unit.

While you wait for your appointment: good habits

A few simple steps help the doctor and protect you:

• use pads rather than tampons, so the amount can be judged;
• note the time it started, the colour and how the bleeding changes;
• avoid intercourse until the doctor has examined you;
• take no medicine without advice, even your usual painkiller;
• gather your results: test, blood tests, previous scans.

Above all, do not stay alone with your worry. Early pregnancy signs can be confusing: our article on the first symptoms of pregnancy helps you sort them out.
