It's one of the first signs of pregnancy, but for most mums, morning sickness can strike at any time of the day - morning, noon, evening and even through the night.
Although there are a lucky few who don't suffer at all, for many it lasts for the whole of their first trimester, and for others, for the whole of their pregnancy! If you're feeling nauseous at the mere thought of food, it can be a comfort to know that morning sickness almost always comes as a sign of a healthy pregnancy.
There are things you can do to keep the queasiness at bay...
What causes morning sickness? Now you're pregnant, your body is naturally producing more oestrogen and your sense of smell is becoming sharper.
There's a theory that we've developed this heightened sense through the ages as a protective reaction to help us detect dangerous or 'off' foods that could cause baby harm.
But just as the severity of morning sickness suffered from mum to mum can differ, so can the triggers which set it off and the methods of easing it.
Ways to ease your morning sickness When it comes to relieving your nausea, it's a case of different strokes for different folks.
Lots of mums report that what works one day doesn't work the next but it's worth giving lots of different things a try to see what works for you.
oAs soon as you wake up, eat something plain and dry like a cracker or piece of wholemeal toast and don't get up for 20-30 minutes.
oYou'll no doubt be well aware of which foods set you off; do your best to avoid them.
While it's ideal to try and eat a balanced diet, it won't cause your baby harm if you stick to dry biscuits and water - or whatever you can manage - for the first few weeks.
oLots of mums report that protein and carbs are the easiest to stomach.
Combine the two; try an egg on toast, or a plain baked potato with baked beans.
oVitamin B6 has long been used to ease morning sickness.
B6 is naturally found in foods like bananas, brown rice and nuts but if you can't stomach them, try a supplement.
oIf, along with your nausea, you're feeling chilly and are longing to stay wrapped up warm, ginger can be beneficial.
Try ginger ale or ginger tea.
Sadly, packets of ginger biscuits are not recommended, although you'll be forgiven for indulging if they help! oIf you're feeling more hot and bothered as well as sickly, peppermint or spearmint tea may be a better choice to help cool you down and calm your stomach.
Sugar-free mints or chewing gum can be good if you're on-the-go.
oRelax and re-charge your batteries; stress and tiredness can make things worse.
Morning sickness can be debilitating and exhausting, but allow yourself time away from work and get friends and family to help with the cooking if it's a bit much.
Not feeling it? Don't worry.
Some mums have it, some mums don't.
And some mums think they've escaped it, only to suffer later on! However unpleasant it is, morning sickness can be reassuring to lots of mums who take it as a sign that their pregnancy is as it should be.
Yet others who can't keep food down worry that their baby isn't getting the nutrients they need.
If you're worried either way, just check with your doctor or midwife and they'll be able to confirm whether everything is OK.
