Most women suffer from morning sickness in the first trimester of pregnancy. Nausea often occurs as a response to strong odors. Identify which odors trigger your nausea and try to keep away from such strong and pungent odors. You can enroll yourself in wellness activities like yoga classes and attend sessions in the morning to help you distract from the feeling of nausea. Taking a stroll outdoors in the early morning and getting plenty of fresh air is also helpful in alleviating morning sickness.
