Sayang, nie memang serious condition yang kena monitor closely masa pregnant dan after birth, so I really think you should sit down with your obstetrician or paediatrician to discuss properly, they boleh explain best based on baby's specific situation, sebab setiap case lain-lain. A few of my mum friends pun ada yang went through congenital heart issues, and honestly the experience and prognosis really depends on the type of defect and severity, so doctor punya guidance is super important. Wishing your baby all the best, and do join some online support groups for parents with babies with heart conditions, they're really supportive and banyak real stories that might help you feel less alone in this journey
