First signs of pregnancy

So, what are the first signs of pregnancy? There are a few tell-tale signals that will give you an idea that you’re pregnant, even before the official test can confirm it. Here are some of the most common symptoms of pregnancy in first month:

  • Nausea
  • Tiredness
  • Light-headedness
  • Constipation
  • Going off things like coffee/tea/fatty food
  • ‘Metallic’ taste in mouth
  • Increase in vaginal discharge (without irritation/soreness)
  • Light ‘implantation bleeding’ (when the egg attaches to the womb)
  • Changes in your breasts: tender, larger, tingling, veins showing, darker/more pronounced nipples
  • Changes in mood
  • Missed period: the most obvious sign, at the end of the first month

The first trimester: what to expect

Your body will go through some incredible changes in the first three months of pregnancy. Many of the first signs of pregnancy will continue to affect you throughout the first stage of pregnancy. Here’s our guide to what to expect in the first trimester:

  • Emotional changes: pregnancy hormones can make you forgetful, moody or unable to focus.
  • Skin changes: as the body makes extra blood, your veins might become more noticeable, and you might get that ‘glow’. You might also get spots due to an increase in oil. You might want to switch to gentle products for your skin and laundry, like the hypoallergenic and dermatologically tested Comfort Pure Fabric Conditioner and OMO Sensitive – ready for when baby arrives, too!
  • Breast changes: hormones preparing your body for breastfeeding might make breasts tender and swollen, with small bumps around your nipples.
  • Vaginal changes: you might experience thin, white discharge or a little spotting. If you experience vaginal bleeding contact your doctor – if it’s painful or heavy – then go to the emergency department.
  • Bladder changes: you might need to urinate more often or experience constipation.
  • Digestion changes: you might experience heartburn.
