In Edinburgh, you only get one scan - so they do it late, 13 weeks. You also aren't seen at all first trimester unless you have bleeding or other complications or a pre-existing medical condition.
I just had my 'booking in' appointment w/the midwife (all antenatal care is midwife lead) yesterday and I'm 14 weeks along. Just had my 'booking' in scan at 13 weeks. You can pay privately for an earlier, dating scan for £50. You can also pay for a 20 week, abnormality scan privately for £140. The NHS will not tell you the sex of the baby (at 13 or 14 weeks, it's usually too soon to tell anyway), nor will they give you a 20-week scan unless they suspect something is wrong w/the baby.
W/second pregnancies, you don't have as many checks unless you had a problem w/your first pregnancy or have an underlying medical condition like diabetes or hypertension. Uncomplicated deliveries are done by midwife.
One thing I won't do again is have a baby in summer. Edinburgh Royal Infirmary is so hot, they tell you to bring your own fan! I was just in there last week for a tummy bug, and they had to put a fan in my room!
I'm hoping I don't have to stay in this time round, b/c you cannot book a private room there (you can at St. John's Infirmary, which is not in Edinburgh but in West Lothian, for £120/night), and will be sharing a room w/3 other ladies and their crying newborns. Also, there is no 'well baby' nursery, only a NICU, so babies must 'room in'.
It is possible to be discharged to home right from the delivery suite, so here's hoping!
You can also have a homebirth. In fact, the midwife yesterday was just telling me about a lovely homebirth at the weekend - the mum delivered in her own tub and it went off w/o a hitch.
