It is completely normal to not experience any pregnancy symptoms, such as morning sickness or tiredness, at 6 weeks. Every woman's body reacts differently to pregnancy, and some may not experience these symptoms until later on or may not experience them at all. Lack of symptoms does not necessarily indicate a problem with the pregnancy. However, if you have concerns or are experiencing other unusual symptoms, it is always best to consult with your healthcare provider for reassurance and guidance. They can provide personalized advice based on your specific situation and medical history.
