Does your previous Dr know how long you have been TTC? Usually any couple who have been trying for over 12 months are entitled to testing. I would see if you can speak to the practice manager at your old surgery and demand that she be told that age does not matter when it comes to fertility testing. It is length of time TTC. I would have told that GP that you want to be FINISHED having children by then and she has no right to tell you when you are 23 that you are 'Too Young'. Just because she is not interested in being a younger mum doesn't mean everyone isn't. I am about to finish my family at 23 and I wouldn't have it any other way. Good luck hun, I hope you get the answers you deserve.
