If you are six weeks pregnant and experiencing nausea, there are several options you can consider. Your local pharmacist can evaluate your symptoms and prescribe medications to help alleviate them. Some common non-pharmacological tips include eating small meals, avoiding greasy foods and strong smells, and not lying down immediately after eating. Additionally, there are prescription medications available such as Diclectin and Gravol that can help with nausea and vomiting during pregnancy. It's important to consult with a healthcare professional for personalized advice and guidance on managing your symptoms.
