I am 19 weeks pregnant i had my morphology ultrasound scan yesterday and today i went to the doc she told that the placenta has only 2 cords and the baby has only one kidney! Does anybody went through that? Is it possible that the ultrasound couldnt be done properly! I am so much worried and crying since i got to know in the morning. Please share your experience!
