Morning sickness can send the bravest mums in a beeline to the nearest bathroom stall in a matter of minutes. The name itself is misleading as morning sickness occurs throughout the day. The Duchess of Cambridge, Kate Middleton, herself had to be hospitalised due to extreme morning sickness. Nausea and vomiting is suffered by a majority of women during their first trimester, marking the beginning of a long, yet ultimately rewarding, journey into pregnancy.
