20 week scan disappointment

deleted account

So upset with how today went and just no peace of mind at all! I had a 12:30 appointment and got there early 12:00 I work nights so only got about 3 hrs of sleep, and I waited in the front lobby an hour before I was called back and then I got changed and waited another 45 minutes! And I had an appointment with my doc at 2:00 to follow the scan and by this point it was 2:00 and I hadn’t even had my scan yet! Finally I get in to get the scan done and the tech doesn’t say a word the entire time not one thing! And baby wouldn’t move around so I had to walk and do stretches and roll around on the table and was in there for an hour and then she was like ok I’m done here’s your picture and she gave me one pic of the profile and a pic of lower extremity and a NL pic that I don’t even know what it is, lol. So I go upstairs to my doc appointment the doc wasn’t there any more so I saw the nurse she didn’t tell me much about the ultrasound and just scheduled me for my 24 week appointment :/ sad that this was the last time I’ll see our baby girl and the whole time I was so worried cause the lady wouldn’t say anything so I don’t know if it’s normal or not
