The short answer: Bleeding in pregnancy doesn't always mean something is wrong. Light spotting is fairly common, especially in the first 12 weeks, and many women who bleed go on to have healthy babies. But bleeding can also signal miscarriage, an ectopic pregnancy or a placenta problem, so always call your doctor or maternity hospital the same day. Heavy bleeding, severe tummy pain, shoulder-tip pain or feeling faint need emergency care: call 112 or 108.
What bleeding in pregnancy can look like
Bleeding in pregnancy ranges from a few drops to a heavy flow. It may be constant, or it may come and go over hours or days. Knowing how to describe it helps your doctor a great deal.
-
Spotting: a few drops of pink, red or brown blood, often noticed on underwear or when you wipe.
-
Light bleeding: enough that you need a pad, but it doesn't fill quickly.
-
Heavy bleeding: soaking a pad soon after you put it on, sometimes with clots or lumps of tissue.
Colour gives clues too. Bright red usually means fresh, active bleeding. Brown or dark blood is usually older blood that has taken longer to leave the body. Pink often means a small amount of blood mixed with discharge. None of these colours on their own tells you whether a pregnancy is healthy, so the advice is the same: get it checked. Our period blood colour chart explains what different shades usually mean outside pregnancy.
Bleeding in the first trimester (up to 12 weeks)
This is when bleeding is most common. Possible causes include:
Implantation bleeding
Light pink or brown spotting when the fertilised egg settles into the womb lining, usually around the time your period would have been due. It's harmless and often happens before you even know you're pregnant. Our guide on whether you can have a period while pregnant explains how it differs from a period.
Changes in the cervix
The cervix, the neck of the womb, has extra blood supply in pregnancy, so it can bleed lightly after sex or an internal examination. This is usually harmless but should still be mentioned to your doctor.
Infection
A vaginal infection, urine infection or sexually transmitted infection can cause spotting, often with itching, unusual discharge or burning when you pee. Our guide to vaginal infections describes the common signs.
Miscarriage
The main sign of miscarriage is vaginal bleeding, which can range from spotting to heavy bleeding with clots. Other signs include cramping pain low in the tummy, passing pink, grey or white lumps of tissue, or a sudden leak of fluid. Some miscarriages cause no symptoms and are only found at a scan.
Ectopic pregnancy
Here the pregnancy grows outside the womb, usually in a fallopian tube. According to the NHS, about 1 in 90 pregnancies is ectopic, and symptoms usually appear between 4 and 12 weeks. Watch for pain low on one side of the tummy, bleeding or a brown watery discharge, shoulder-tip pain and discomfort when peeing or pooing. A ruptured tube is an emergency that needs surgery.
Molar pregnancy
A rare condition where the pregnancy doesn't develop properly. It can cause bleeding and is diagnosed on a scan.
Bleeding in the second and third trimesters
Bleeding after 12 weeks is less common and should always be checked promptly. Causes include:
-
Placenta praevia: a low-lying placenta that covers part or all of the cervix. It often causes painless bright red bleeding. Your anomaly scan around 18 to 21 weeks checks where the placenta sits.
-
Placental abruption: the placenta starts to come away from the wall of the womb. It usually causes pain as well as bleeding, and is an emergency.
-
Cervical changes or infection: as in early pregnancy.
-
Late miscarriage or early labour: bleeding with regular tightenings or cramps before 37 weeks needs urgent assessment.
-
A "show": near your due date, the sticky, jelly-like mucus plug from the cervix can come away. It's often pink from a little blood. If you're losing more than that, phone your hospital straight away.

When to call your doctor and when it's an emergency
Call your doctor or maternity hospital the same day if
- You have any spotting or light bleeding, even with no pain.
- You have bleeding with mild tummy pain that doesn't stop you doing everyday tasks.
- You have bleeding with diarrhoea, or pain or pressure when you pee or poo.
- You notice bleeding after sex.
Get urgent help straight away if
Call 112 or 108, or go to the nearest hospital emergency department, if you're bleeding and have:
- Severe tummy pain that stops you focusing or doing anything else.
- Pain in the tip of your shoulder.
- Feeling sick, faint or dizzy, looking very pale, or passing out.
- Heavy bleeding that soaks a pad soon after you put it on.
- Bleeding with your baby moving less than usual, later in pregnancy.
Don't drive yourself. Ask a family member or neighbour to take you, or call an ambulance. In many Indian cities and towns, 108 connects you to a free government ambulance service.
What to do while you get help
-
Use a pad, not a tampon or menstrual cup. This lets you and your doctor see how much you're bleeding and what colour it is.
-
Keep a simple record: the time it started, the colour, roughly how many pads you've used and whether you've passed clots or tissue. If you can, keep any tissue in a clean container for the doctor.
-
Bring your pregnancy file: your hospital card, scan reports and blood test results help the team understand your pregnancy quickly, especially if you're seen somewhere new.
-
Rest until you've been seen, and avoid heavy lifting.
-
Don't take any medicine without checking with your doctor first. For pain, ask before taking anything, as some painkillers aren't recommended in pregnancy.
What the doctor will check
Your doctor will ask how many weeks pregnant you are, when the bleeding started, how heavy it is, whether you have pain, and about any earlier pregnancies or bleeding. Then they may:
-
Examine you: feeling your tummy and, sometimes, a gentle internal examination to look at the cervix.
-
Do an ultrasound scan: on your tummy or, in early pregnancy, with a small probe inside the vagina, which gives a clearer picture. It's safe for the pregnancy.
-
Take blood tests: to check pregnancy hormone levels, your haemoglobin (for anaemia), and your blood group. If your blood group is Rh negative, you may need an injection to protect future pregnancies.
-
Test your urine: to look for infection.
Possible treatment
Treatment depends on the cause and how far along you are. It could be no treatment at all if the pregnancy is healthy, closer monitoring (sometimes in hospital), medicine, or surgery, for example for an ectopic pregnancy. Later in pregnancy, it may mean induction of labour, or a caesarean if the placenta is the cause.
If you have a miscarriage
If you are reading this after losing a pregnancy, we are so sorry. A miscarriage can feel shocking and lonely, even when it happens very early and few people knew you were pregnant.
Please know that a miscarriage is usually linked to a problem with how the pregnancy was developing. It is very unlikely to be caused by anything you did. Going to work, travelling, normal exercise, having sex, or eating spicy or so-called "hot" foods that relatives may mention are not things to blame yourself for.
Physically, your doctor will explain what to expect. Bleeding and cramps can continue for a while, and sometimes medicine or a small procedure is offered. Ask what bleeding is normal for you and when to come back. Using pads rather than anything inside the vagina makes it easier to see if the bleeding is settling. Some women find soft disposable period panties, which are worn once like underwear and are absorbent all around, more comfortable at night during this time.
Emotionally, there is no right way to feel. Grief, numbness, guilt, anger or relief can all be part of it, and partners grieve too. In joint families, well-meaning advice can sometimes feel like pressure. It's okay to say you need quiet, to take time off, and to talk about your baby, or not, as you wish.
If sadness, anxiety or trouble sleeping stays with you, or you feel unable to cope, please reach out. Tele-MANAS, the government's free mental health helpline, is available on 14416. Your doctor can also connect you with a counsellor. If you ever feel unsafe, call 112.
Frequently asked questions
Is spotting normal in early pregnancy? It's fairly common, and many women with spotting have healthy pregnancies. It should still be checked the same day, because the causes vary.
Can bleeding after sex in pregnancy be normal? The cervix can bleed lightly after sex because of its extra blood supply. Tell your doctor, so other causes can be ruled out.
Does bleeding always mean a miscarriage? No. Many women bleed in pregnancy and go on to have a healthy baby.
Is brown blood in pregnancy less worrying than red? Brown blood is usually older blood, and light brown spotting is often harmless. But colour alone can't rule out a problem, so call your doctor either way.
Should I go for bed rest if I'm spotting? Follow your doctor's advice. Resting until you've been seen is sensible, but strict bed rest isn't always needed once the cause is known.
Can I have a healthy pregnancy after a miscarriage? Yes. Most women who have a miscarriage go on to have a healthy pregnancy later. Talk to your doctor about when you feel ready to try again.
What does bleeding with pain on one side mean? It can be a sign of ectopic pregnancy, especially before 12 weeks. Get urgent help, particularly if you also feel faint or have shoulder-tip pain.
