On your first consultation, the dr. would recommend to you the most appropriate method (whether it's iui or ivf) for you.
If you can confirm which treatment to go for (iui or ivf), you and your husband will be asked to ask a bunch of letters and agreements. (For IVF, I assumed you have attended the seminar)
On the same day, you and your husband will need to take some blood test (eg. HIV). The nurse (or doctor) will also tell you which month you will start your treatment. It could be at least 2 months after your first consultation because they cannot start your treatment before the blood test result is released.
