The Motherisk Nausea and Vomiting of Pregnancy (NVP) ForumMotherisk receives questions from around the world about morning sickness symptoms, effects, treatments and ways to cope. Those questions and answers are posted here for anyone to read, provided the reader acknowledges and accepts the proviso and disclaimer below.
At the start of 30 weeks, I have been experiencing nausea in the mornings again. I have vomited bile on two occasions. I did not experience this nausea with my first pregnancy. Can a person experience nausea in the last trimester? Would I be just fighting a virus? Thanks.
NVP can occur and start anytime in pregnancy, although most women suffer in the first three months. If it persists for more than a week, you may have NVP, in any case you should consult with your physician to rule out any other causes.
