Hello, could you please tell me if anyone has ever given birth with Williams syndrome (lack of factor VIII in blood)? I just went on record a few days ago... so the doctors scared me... they started saying "how did you even get pregnant?" "you can't carry it" although they don't understand what this disease is... they don't know because they keep telling me to stop my nails from bleeding or I'll hurt myself and the blood won't stop ?‍♀️ The first trimester was great, everything was fine, there were no pain, no discharge, now I'm worried how the delivery will go ? Of course, it's still early to think about it, but now I'm scared,
