I went to my 20 week scan this morning. My OB is sending me to a specialist, to take a look at baby's stomache. She said everything looks good but couldn't look at the stomache good "because of the baby's position" . She was going to check in 4 weeks but then decided I should just go see the specialist. Wich I will wait for a call. She said its nothing to worry about. But then she mentioned I need to send you and make sure the bubble is nothing bad?! Bubble? She never said anything about a bubble. Should I be worry? What can I expect?
