Morning sickness can happen at any time of the day, and it can happen all day. I know, it sucks, but it should be over by the time you hit your second trimester, but everybodys pregnancies are different. It is completely normal, and you are not harming your baby. Just make sure you are taking your vitamins, and eating healthy. Some people are unlucky and have morning sickness throughout their entire pregnancy. Try eating some saltines in the morning before you even get out of bed, and eating small, but frequent meals may help also.
