Nausea is a common complaint during pregnancy, and is usually nothing to worry about. During pregnancy, your body undergoes a number of changes - these include a change in hormone levels, some increase in the amount of stress, and a change in the way your digestive system functions. Usually, the nausea is worst in the morning, which is why it is usually known as "morning sickness"; however, it can occur at any other time of the day too. Occasionally, the sensation of nausea can be strong enough to make you throw up. This is not abnormal or harmful to you or the fetus, and you should therefore avoid stressing yourself over it.
Some simple measures can help control the nausea and thus minimize the chances of you throwing up. First of all, you should just avoid foods that make you feel nauseous - avoid eating them, avoid cooking them, and avoid having them cooked in the house as well, unless they are absolutely necessary. As you have probably already noticed, even the smell of certain foods can bring on a feeling of nausea. Foods that are oily or spicy are common culprits, and it is usually a good idea to avoid them. Instead, eat light foods that are rich in carbohydrates or even protein. Secondly, you should eat smaller meals and eat more frequently, instead of eating two or three large meals a day, as both a very full stomach and a completely empty stomach can make you feel nauseous. Do not worry too much about overeating - right now, both your baby and you need a lot of nutrition, and as long as you don't go completely overboard, you can eat whenever you feel hungry.
When you wake up in the morning, you should get out of bed slowly. Sit up in bed for a few minutes, and only then get out of bed. If you can, you should even have breakfast in bed - if this is not possible, simply keep a fruit by your bedside. Give yourself some time to feel fully awake, then eat the fruit, wait for a few minutes and only then get out of bed.
Whenever you do feel nauseous through the day, sit down, close your eyes, and breathe deeply. If this does not help, you can sniff a lemon or even drink some lemon juice or fresh lime soda. And finally, some consolation - the nausea usually persists only for the first trimester, so you can look forward to it ending soon enough.
