Oh sayang, I'm so sorry you're going through this again, that must be incredibly heartbreaking. Please follow through with the amniocentesis testing this week , and make sure your doctor refers you to a maternal-fetal medicine specialist or genetic counselor if they haven't already, because recurring cases like yours need expert eyes to find answers. A few of my mum friends who faced recurrent losses said having a specialist team, not just OB, made all the difference in understanding what's happening and what options exist for next time. You deserve proper investigation, not guessing. Sending you so much strength through this. Take care of yourself emotionally too, okay?
