In some cases, it is possible for a foetal pole to be visible during an ultrasound at 7 weeks without a clear view of the heartbeat. The visibility of the heartbeat can vary depending on factors such as positioning and equipment used. An internal ultrasound may provide a clearer image and increase the chances of detecting the heartbeat. It's important to remember that every pregnancy is different, and there can be variations in when certain milestones are reached. While it is natural to feel worried, try to stay positive until you receive further information from your healthcare provider. They will be able to provide you with more accurate information based on your specific situation. It's reassuring that you haven't experienced any bleeding or pain so far, as these can sometimes indicate potential issues. Remember to discuss any concerns or questions with your healthcare provider, as they are best equipped to provide guidance and support throughout your pregnancy journey.
