I saw the perinatologist today. It was reassuring. He is very easy to talk to. He prescribed a dating scan to give me peace of mind. I have that scheduled for next Tuesday. I'm pretty nervous about it. I haven't had a lot of positive u/s scans over the past few years. He also recommended I touch base with my thoracic surgeon to make sure that everything will be okay, because I had a giant hiatal hernia repaired about a year ago, and we want to make sure it's not going to be a problem during labor. I really have baby brain, though, because I told him I had my surgery in July, then I was thinking about it this evening, and it was July of last year. I have to call him back and tell him that little detail.
