Have you thought about going to Zita West? She is a fertility specialist and you can make an appointment to go to her clinic in London and see her or one of her staff. You can even have a consultation over the phone. You can fill in a contact form online and they'll call you back within 24 hours. Not sure how much it'll cost but might be about the same as going private anyway?
