Early signs of pregnancy

For women who have a regular monthly menstrual cycle, the earliest and most reliable sign of pregnancy is a missed period.

Women who are pregnant sometimes have a bleed similar to a very light period, with some spotting or only losing a little blood. This is called implantation bleeding.

Some of the other early pregnancy signs and symptoms are listed below.

Every woman is different and not all women will notice all of these symptoms.


Feeling sick during pregnancy

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

For most women who have morning sickness, the symptoms start when they're around 4 to 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.

Feeling tired is common in pregnancy

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.

Strange tastes, smells and cravings

You might notice:

  • 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 your pregnancy test is negative

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.
