Hi Emma
It sounds like you have been seen the right amount of times, every time I have been in to see the midwife I have asked when should my next appointment be and then made the appointment on the way out. I have only been to the hospital for my scans I see the midwife at the doctors surgery. I saw the doctor first to confirm at 6 weeks, then had booking in at 10 weeks, dating scan at 13 weeks, midwife check at 16 weeks, anomly scan at 20 weeks and midwife check at 25 weeks. I have had to book all my own appointments and my next is at 28 weeks.
however you should have been given your notes at your booking in appointment and then been taking them with you, I would ask where they are and why you don't have them, you may find that your test results have just been put in the file. If there was a problem I'm sure they would have contacted you.
Take care
