| I am 18 weeks pregnant and was just told my baby boy has a single umbilical artery. The doctor wants to check me again at 22 weeks. The baby's weight is at 1/2 pound right now and the doctor wants him to grow for a better scan (I guess). I'd like to know where I can get reliable information on this. I can't seem to find any articles that agree with each other. Is my baby going to have a birth defect because of this? What are the odds? The doctor told me it was 99% that he would be fine but everything I have seen online is putting it more at 50%. My doctor is a Maternal Fetal Specialist and I believe he wouldn't lead me on, but is this more serious than I was led to believe? I just want to be prepared if my baby need special attention. What kind of defects are most common and where can I find information on that? Thank you for your prompt reply. |
