Anyone have this??

I went for my 20 week ultrasound and had to do a repeat because they couldn't see some stuff I go back and they saw everything BUT in both ultrasounds it said he has a distended stomach and now my doctor is sending me to a specialist and getting the "better" ultrasound. Im so worried she didn't say what it could be cause she didn't want me to google when it could be nothing. Doesn't make me worry less and I'm waiting on them to call me for my appointment.
