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.
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.
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.
Tiredness during pregnancy can also be caused by , which is most commonly caused by . 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.
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.
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.

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 . Exercising in water can reduce back pain in pregnancy, and and may also help.
At the onset of pregnancy the hormone progesterone increases your 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:
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:

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.
Heartburn and indigestion
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), and (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.
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.
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.
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 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 as soon as possible.
Tingling and numbness in your hands (carpal tunnel syndrome)
Carpal tunnel syndrome may be mild, intermittently painful, or severe, which may cause partial paralysis of the thumb or loss of sensation. Symptoms usually resolve on their own soon after birth.
If you are experiencing tingling and numbness in your hands, inform your doctor or midwife. In very severe cases, your doctor may recommend corticosteroid injections or surgical treatment.
An increase in vaginal discharge is a common change during pregnancy. If it is associated with itchiness, pain, a bad odour or pain on passing urine then it may be due to an infection. Seek treatment from your GP.
Vaginitis is inflammation of the vagina, and is a distressing complaint for many women. It is more frequent during pregnancy. Some causes of vaginitis include , , and . See your GP for diagnosis and treatment
Varicose veins and leg oedema (swelling)
of the legs are very common in pregnancy due to a combination of factors, including increased volume of circulating blood during pregnancy, and pressure of the pregnant uterus on the larger veins. This increased pressure on the veins can also result in swelling of the legs (oedema) that can cause pain, feelings of heaviness, cramps (especially at night) and other unusual sensations.
If you have varicose veins, it is recommended that you:
- Wear support stockings.
- Avoid standing for long periods.
- Exercise gently and regularly (walking or swimming).
- Lie down to rest with feet elevated, when you can.
- Try massaging your legs.
- Tell your doctor or midwife at your next pregnancy visit.
