Yes, it is normal to start experiencing nausea and vomiting around 12 weeks into pregnancy. It is important to ensure you are not losing a significant amount of weight. Diclectin can be very effective in relieving these symptoms. In addition to medication, there are complementary methods like wrist acupressure, eating small but frequent meals, snacking on dry biscuits, and staying hydrated to help alleviate nausea. It is also recommended to consult a doctor if nausea is new and starts after the 9th week of pregnancy, as it could be related to other issues like reflux. Medications like omeprazole and Gaviscon can be helpful in managing these symptoms. If necessary, you can also take Gravol while waiting to see a doctor.
