It is not uncommon for some women to experience little to no symptoms during the early stages of pregnancy, including at 9 weeks. Every woman's body reacts differently to pregnancy hormones, and while some may experience morning sickness and other symptoms, others may not. As long as your sonography results are normal and you are not experiencing any concerning issues such as severe abdominal pain or bleeding, there is usually no cause for alarm. However, it is always a good idea to consult with your healthcare provider if you have any concerns or questions about your pregnancy. They can provide personalized advice based on your specific situation and medical history.
