Pregnancy tip

If you have any worries about new symptoms during pregnancy, it is best to talk to your midwife or GP.

Pregnancy symptoms to watch out for

Which pregnancy symptoms are normal and which should you talk to your GP about?

Pregnancy brings with it a large number of experiences and symptoms that can feel unusual. For the most part, they are completely normal. However, you should be aware of some of the warning signs that mean you need to contact your midwife or GP.

In certain circumstances these can include abdominal pain, bleeding, headaches, leg discomfort and breathlessness.

Abdominal pain

Abdominal pain can be caused by trapped wind, indigestion, heartburn or ligament strain. If you also experience:

  • severe pain in the upper right abdomen, especially if you also have headache or swelling and/or
  • bleeding, with or without tight feeling abdomen,

you should contact your midwife.


Bleeding can occur:

  • early on in your pregnancy around the time you would have had a period (usually this is slight)
  • after sex if there is a sensitive or sore spot on the neck of your uterus (cervix)
  • with urine or kidney infections
  • with a placental abruption, which is when the membranes around the baby become slightly separated from the wall of the uterus
  • with a show or
  • with placenta praevia (a low lying placenta) at the onset of labour.

Always consult a midwife or GP about bleeding. Before 37 weeks, bleeding can indicate risk of miscarriage, haemorrhage or premature labour.


Headaches have a large number of causes including dilated blood vessels, stress and dehydration. But if you have a headache accompanied by:

  • generalised swelling, particularly if this has started suddenly
  • flashing lights in your eyes or
  • if you know your blood pressure has been increasing,

you should call your midwife straight away.

Pain in the legs

Leg discomfort can result from swelling, trapped nerves, cramp, or varicose veins. Call your midwife if there is redness, swelling and heat in one calf, and there is pain on bending the foot on that side.


Breathlessness can result from extra weight to carry, or from anaemia. Call your midwife if onset is sudden, and accompanied with chest pain.

If you have any worries about new symptoms during pregnancy, it is best to talk to your midwife or GP.
