If you have a regular monthly menstrual cycle, the earliest and most reliable sign of pregnancy is a missed period.

In the first few weeks of pregnancy you may have a bleed similar to a very light period, with some spotting or only losing a little blood. This is called implantation bleeding.

Every pregnancy is different and not everyone will notice all of these symptoms.

You may feel sick or be sick. This is commonly known as morning sickness, but it can happen at any time of the day or night.

Morning sickness symptoms usually start when you’re around 4-6 weeks pregnant

If you're being sick all the time and cannot keep anything down, see a GP.

You may have hyperemesis gravidarum, a serious condition in pregnancy that causes severe vomiting and needs treatment.

It's common to feel tired, or even exhausted, during pregnancy, especially during the first 12 weeks or so.

Hormonal changes in your body at this time can make you feel tired, sick, emotional and upset.

Your breasts may become larger and feel tender, just as they might do before your period. They may also tingle.

The veins may be more visible, and the nipples may darken and stand out.

You may feel the need to pee more often than usual, including during the night.

Other signs of pregnancy you may notice are:

constipation
more vaginal discharge (without any soreness or irritation)

During early pregnancy, you may find you no longer like some foods or drinks you used to enjoy.

You might notice:

a strange taste in your mouth, which some describe as metallic
you crave new foods
you lose interest in certain foods or drinks you used to enjoy, such as tea, coffee or fatty food
you lose interest in smoking
you have a more sensitive sense of smell than usual – for example, the smell of food or cooking

If you're worried about any symptoms you're having, talk to a GP or your midwife.

A positive test result is almost certainly correct, as long as you have followed the instructions correctly.

A negative result is less reliable. If you get a negative result and still think you may be pregnant, wait a week and try again.

If you're pregnant, use the pregnancy due date calculator to work out when your baby's due.

Significant hormonal changes take place during pregnancy. These trigger a variety of symptoms. Some women experience many of the symptoms of pregnancy, while others may have only a few.

Symptoms of early pregnancy include missed periods, breast changes, tiredness, frequent urination, and nausea and vomiting (morning sickness). However, these symptoms may be caused by other factors and do not necessarily mean that you are pregnant, so if you suspect you are pregnant take a home pregnancy test and see your GP.

A wide range of changes can occur in your body in the later stages of pregnancy, including backache, headache, leg cramps or varicose veins, itch or tingling, constipation, haemorrhoids or indigestion, vaginitis or vaginal discharge, or mood changes or depression.

If you have any concerns don’t hesitate to talk to your GP. See your GP right away if you experience symptoms like vaginal bleeding or breaking waters, chronic pain, high temperature, severe headaches or vision loss.

Signs of pregnancy

The signs of early pregnancy can include:

missed period
nausea and vomiting (often called ‘morning’ sickness, but it can occur at any time)
breast tenderness and enlargement
fatigue
passing urine more frequently than usual, particularly at night
cravings for some foods, distaste for foods you usually like, and a sour or metallic taste that persists even when you’re not eating (dysgeusia).

Many of the signs of pregnancy, such as a missed period (amenorrhoea), nausea (morning sickness) or tiredness can also be caused by stress or illness, so if you think you are pregnant take a home pregnancy test (urine test) or see your GP, who will administer a urine test, blood test or ultrasound scan.

Missed period

Missing a period is often the first sign of possible pregnancy. However, some women experience light bleeding around the time of their expected period.

Nausea and vomiting

‘Morning’ sickness is a condition that affects more than half of all pregnant women. The symptoms include nausea and vomiting, and loss of appetite. Many women with morning sickness don’t just get symptoms in the morning but experience them throughout the whole day.

Morning sickness usually begins around the fourth to sixth week of pregnancy and may settle by week 12, although it can continue for longer or return at around 32 weeks.

Breast changes

During pregnancy, the breasts become fuller, swollen and tender. These changes are similar to those you may have noticed in the few days before your period. During pregnancy, the skin around the nipple becomes darker and the veins in the breast become more obvious.

Fatigue

Overwhelming tiredness is common in early pregnancy. This is most likely caused by the massive increase in the sex hormone progesterone. Progesterone is needed to maintain the pregnancy and help the baby to grow, but it also slows your metabolism.

Try to get some more sleep or rest when you can during this early stage. Your energy levels will probably rise again by around the fourth month of pregnancy when the placenta is well established.

Tiredness during pregnancy can also be caused by anaemia, which is most commonly caused by iron deficiency. Eating iron-rich foods is important in the prevention of iron deficiency anaemia during pregnancy. Medical treatment of anaemia in pregnancy usually involves taking iron tablets. Sometimes an iron infusion (iron medicine given by a drip) is needed. This needs a hospital admission but only takes a few hours. Some iron infusions can be given by your GP.

Frequent urination

Pregnancy causes an increase in levels of body fluids and greater kidney efficiency. The swelling uterus also presses against the bladder. As a result, most women start experiencing more frequent urination within the first few weeks of becoming pregnant.

Food cravings

Cravings for certain foods are very common in pregnancy, especially for foods that provide energy and calcium, such as milk and other dairy products. You may also notice a sudden distaste for foods you previously liked.

Some women even develop an unusual taste for non-food items such as soil or paper. This is called ‘pica’ and may indicate a nutrient deficiency. Please speak to your GP or midwife if this develops.

Other symptoms of pregnancy

Many of these symptoms may also be indicative of other conditions. If in doubt, see your GP.

Backache

Back pain during pregnancy can affect more than 1 in 3 women. This is usually due to loosening of ligaments and change in posture due to the growing pregnancy.

You can help reduce back pain during pregnancy by wearing flat heeled shoes, using chairs with good back support, avoiding lifting heavy objects, and doing gentle exercise. Exercising in water can reduce back pain in pregnancy, and physiotherapy and acupuncture may also help.

Breathlessness

At the onset of pregnancy the hormone progesterone increases your lung capacity. This enables you to carry more oxygen to your baby and get rid of waste products such as the carbon dioxide that you both produce. At each breath you breathe more deeply and the amount of air you inhale (and exhale) increases significantly. This can make you feel short of breath.

In addition, as pregnancy approaches term, the pressure of the enlarging uterus and baby on your diaphragm can make your breathing feel more laboured.

Contact your doctor or midwife if you experience sudden onset of breathlessness associated with any of the following:

pain
palpitations (heart pounding)
extreme tiredness
exercise.

Constipation

Constipation refers to infrequent, hard bowel movements that are difficult to pass. Constipation is a common problem in pregnancy that may be caused by pregnancy hormones slowing your gastrointestinal movement, or by the pressure of your growing uterus on your rectum.

If you experience constipation during pregnancy, you are advised to:

drink plenty of water every day.
increase your dietary fibre (such as bran, wheat and fresh fruit and vegetables).
do gentle, low impact exercise such as swimming, walking or yoga.

Don't take over-the-counter laxatives without first consulting your midwife or GP. If changes to your diet and lifestyle don't make a difference then your GP or midwife can prescribe a laxative that is safe to use in pregnancy.

Haemorrhoids (piles)

You may develop haemorrhoids (also known as piles) as a result of straining from constipation or the pressure of your baby’s head. Be reassured, symptoms usually resolve on their own soon after birth.

If you have bleeding from haemorrhoids, itching, discomfort or pain it is recommended that you:

Alleviate or prevent constipation by increasing your daily water and fibre intake.
Sit in warm salty water for about 15 minutes, especially after a bowel motion.
Apply haemorrhoid cream.

If the bleeding or pain continues, talk with your GP (doctor) or midwife.

Contact your GP or midwife if you have a headache during pregnancy that is not relieved by paracetamol (such as Panadol), especially in the second half of pregnancy.

A persistent headache can be associated with pre-eclampsia – a condition that can affect your kidneys and thus increase blood pressure and decrease blood flow to your baby.

Heartburn and indigestion

Heartburn, reflux or indigestion is the pain and discomfort associated with acid from the stomach entering and ‘burning’ the oesophagus.

Indigestion is more common during pregnancy due to the pressure of the enlarging uterus on the organs of the abdomen and the action of the hormone progesterone that relaxes the muscle between the oesophagus and stomach.

If you are experiencing heartburn, reflux or indigestion, it is recommended that you:

Eat small and more frequent meals.
Avoid eating just before going to bed.
Sleep with extra pillows so your head is raised.
Wear loose-fitting clothing.
Avoid any food or fluid that aggravates symptoms – such as fatty foods (including fried foods, fatty meats and pastry), spicy foods (including curry and chilli), alcohol and caffeine (including tea, coffee, chocolate and cola).
Consult your doctor before taking antacids.

If these strategies do not relieve your symptoms, please consult your GP, who may prescribe a medication that will safely reduce the secretion of acid.

Itchy skin

Widespread itching over the body is not common in pregnancy but it can be very distressing, interfering with sleep and enjoyment of pregnancy. Dry skin and eczema are the most common causes but sometimes there may be no apparent cause for the itching. In rare cases, where the palms of the hands and soles of the feet are itchy, it may be due to serious liver disease – a blood test can be done to check for this.

An itchy rash in the later part of pregnancy is thought to be caused by the body’s reaction to the stretching of the skin. This is called PUPPS. Itching can be controlled by using moisturisers and antihistamines. Ask your doctor or midwife what antihistamines are safe in pregnancy.

Leg cramps

Leg cramps occur due to a build-up of acids that cause involuntary contractions of the affected muscles. They are experienced by up to half of pregnant women, usually at night. Leg cramps are more likely in the second and third trimesters.

If you experience leg cramps, it is recommended that during an episode you:

Walk around.
Stretch and massage the affected muscle(s) to disperse the build-up of acids.
Apply a warm pack to the affected muscle(s).

If you find cramps troublesome, discuss with your GP or midwife the option of taking magnesium lactate or citrate morning and evening.

Mood changes

Some newly pregnant women experience mood changes such as irritability. Other pregnant women experience feelings of elation. It is thought that the pregnancy hormones influence chemicals in the brain, causing mood changes.

During pregnancy, 1 in 10 women experience depression. Depression is treatable, so if you are feeling depressed or ‘down’ during pregnancy it is extremely important to get help early. Please contact your GP (doctor), midwife or maternal and child health nurse as soon as possible.
