If your ultrasound did not detect a heartbeat or movement despite a positive pregnancy test, it may indicate a potential issue with the pregnancy. A serum beta HCG reading of 14000mIU/ml suggests that you are still in the early stages of pregnancy. It is important to consult with your gynecologist or healthcare provider for further evaluation and guidance. They may recommend additional tests, such as repeat ultrasounds or blood work, to monitor the progress of the pregnancy and determine if any interventions are necessary. Remember that every pregnancy is unique, and it's essential to seek professional medical advice for accurate assessment and appropriate management of your situation.
