Anatomy scan...

I had my 20 weeek scan today and I have a couple questions. The tech said she isn’t allowed to answer anything so I got no info from her besides the gender and heartbeat. Anyways. My baby was upside down in the pics. Is that normal at 20 weeks? I also have a long cervix? And she said the baby was curled up? Of course I’ll ask my doctor next week when I see him but I figured I’d still ask.
