Hi Mylitta,
You will have a general IVF cycle - there are several varieties available, and for some of them you will be on the pill first.
There are 2 steps for genetic condition PGD - they first have to develop a test, (which takes some time, and which may also have a waiting list), and then they do the actual cycle with the PGD. There will be waiting involved - but I can't tell you how long. I do know that over the last few years the waiting has been reduced as they get better at test development and have more staff in the labs though. I had several years of test development and waiting before getting to do a cycle - but it's not usually so tricky now.
good luck!
