Hi,thanks for query.No,it is not normal.Nausea and
vomiting at nine month needs to be treated energitically as any form of
dehydration or strain to abdomen can lead to problems in
pregnancy.Some kind of discomfort in stomach along with
indigestion is common at this time as enlarged uterus pushes stomach away.Please talk to your doctor and find out the cause.
wishing you good health.
