I don't think ypu'll need a long appointment. They really don't do much at your first appointment. They did a HPT and ordered full bloods, and checked my BP at my first app. He also gave me a referal to an OB. I'm sure your GP will answer a lot of your questions, but she may also recommened asking some of them to your OB (or midwife if you go that way). Write all your questions down cuz you'd be supprised how blank you go when you walk in lol!!!
You must be bursting with excitment about everything!!! Congratulations to you and your partner! Enjoy every moment of your preg, when its all over you'll miss it... I certainly do!!!
Take care
