I'm 29 weeks pregnant and booked in at Harrogate too so thought I'd try to reassure you a litte .
At 20 weeks I had to spend 4 nights on the delivery suite observation ward after a (painless) heavy bleed. When I phoned the delivery suite in a mad panic at 6am they told me to come straight in and when I arrived I was taken very seriously and seen straight away. During the 4 days on the ward (during which I bled heavily again several times) the staff were great and very reassuring, letting me listen to the baby's heartbeat several times a day and just being generally friendly and supportive.
It turned out that the bleeding was caused by a severe cervical ecropion and it wasn't putting the baby in danger which was a relief to say the least!
I've had good feedback about Harrogate from people who have had their babies there and my own recent experience has led me to feel confident that when the time arrives the staff will do their best for us.
Have you been to parentcraft classes or had a tour of the ward? They may help reassure you.
Hope this helps and that everything goes well for you!
