As you may know, increasing HCG levels are one of the reasons for first trimester nausea. However, it can be difficult to determine the exact cause of nausea in the third trimester.
The following could be some of the possible reasons why you are experiencing nausea during the third trimester of pregnancy.
Fluctuating hormones: Frequent changes in your hormones may cause vomiting and nausea in the third trimester.
Growing baby: As your growing baby exerts pressure on your digestive system, you may experience symptoms like heartburn, nausea, and vomiting.
Changes in your body: Bodily changes, sleep disturbances, and stress and anxiety about labour and childcare may lead to vomiting and nausea in the third trimester.
Diet: Consuming too spicy, acidic, and greasy foods can exacerbate vomiting and nausea during pregnancy. Hence, track your diet, and avoid foods that may cause nausea.

This condition is characterised by high blood pressure and can pose serious complications if left untreated. Inform your healthcare provider if you experience nausea accompanied by severe headache and vomiting.
