I'm sorry to hear about your previous loss and the challenges you've faced. While I'm not a doctor, it's important to consult with a healthcare professional for accurate information regarding your specific situation. They can assess your medical history, conduct tests, and provide guidance based on their expertise. It's possible that certain factors may increase the risk of heart problems in subsequent pregnancies, but each case is unique. By seeking medical advice early on and receiving appropriate prenatal care, you can ensure the best possible outcome for both you and your baby.
