Any help would be great

Hi guys. Me and my partner are going for the PGD. Which is basically the same as IVF but due to a genetic gene of which I carry means they are able to remove the gene before putting the embryos back. I was just wondering for anyone who has had either this or the normal IVF what the first appointment consists of? I am getting major anxiety and probably over thinking everything in my head 100 and 1 times. And would help so much if people could put my mind at rest a little bit. Hospitals make me nervous at the best of times. I just do not know what to expect from the first meeting. If anyone could tell me anything I would really appreciate it ❤❤
