Hi, As this vomiting is of a relatively recent onset, infection should also be considered and so is indigestion. As the uterus enlarges into the abdominal cavity, it pushes on the stomach and as a result, it becomes difficult to eat a full meal and also to digest it. Electrolyte imbalances, urinary infections and abnormal blood pressure are the other conditions that need to be ruled out. Please check with a physician for proper management. Take small and easily digestible meals. Wish you good health.
