Morning sickness, when does it start? And, can I do anything to help?

There is a big range of morning sickness, and it can vary from pregnancy to pregnancy, symptoms are often described from anything such as a bad hangover, really bad motion sickness to the more severe version known as Hyperemesis Gravidarum (HG) which affects around 2% of all pregnant women. If you are vomiting multiple times in the day, having trouble keeping fluids and food down - you may have HG. You should seek medical advice, as you may be at risk of serious dehydration.
