Thanks all!
I know, I honestly have no idea! And my partner keeps suggesting ridiculous names - Xerxes anyone?!

The sonographer said she's very happy with the baby and all her comments when she was checking everything were "very nice", "perfect", so that's given me a lot of reassurance.
My mum has messaged me a couple times asking when my appointment was, but I still feel so sour about her reaction last week and how "disappointed" she was and "doesn't want to be a grandma" that I've been ignoring her, I do feel a bit bad though.
