I went to the ultrasound appointment and the doctor said she seen a bright speck/ dot on the baby's heart but that not to worry it's a normal thing that my test came fine for the meternal fetal doctor. It kind of freaked me out because I would like to know more about the dot on the baby's heart. What could it be?

I'm so sorry but we really can't answer this for you. It really is best that you speak to your doctor about any concerns you have. Trying to guess what this could be, would be like trying to predict what will happen in the world, all over the world, tomorrow. Without the data needed, there's really no way to even guess.

Please discuss your concerns with your doctor. No question is silly. Keep asking until you get the answers, if you don't understand something, tell your doctor you don't understand. Your doctor really is the only one with enough info to answer your concerns.
