@Lostintranslatio good luck with the scan, it'll be nice for you to get your date :-). You don't need to fast for the bloods so don't worry about that.
First time posting here, I'm 16+4 today, 1st baby, had my 16 wk appointment on Tuesday and was just fab to hear that heartbeat again!
Felt my first fluttering 2 days ago and have felt more since, it's just so amazing!
