I think the first appointment now with a midwife is an hour long and it's just general health questions, filling in forms etc. You'll have bloods done which test blood group, antibodies, HIV or any diseases like that. 3 years ago when I had my first appointment when I was pregnant with my son, it was 20 mins and was just blood. They've changed the whole system now. She will send off a booking form for your u/s (whereas 3 years ago the Dr sent off for it as soon as you got pregnant). Hope that's enough info xx
