I just feel like crying at the moment. I just found out I have antibody Lewis A. I have to do monthly blood work done and the dr decides based on my levels weather or not to deliver the baby early 😔😔 this is heartbreaking I'm only 21 weeks... I hope I atleast make it close to full term before they say I have to deliver him early at any point now I know my son won't survive.. I'm so devastated because I just felt like something was wrong w this pregnancy. And now this 😩😩. Idk even know how to tell my boyfriend. He is gunna think it's my fault. He won't understand..
