Hi Kate
Sorry you're feeling so let down and disappointed with your clinic. This whole process is a massive pile of shit. I totally get your frustration with everything taking so long, the whole process of investigations seeming so drawn out and it all just feeling like waiting, but nothing actually happening. I well remember writing a massive rant about it (elsewhere) at the time and I really feel for you.
To answer your questions: at my first appointment (NHS) they did an AMH blood test and I think rubella antibodies. They also referred me for a HSG.
I had the HSG 2-3 months after the appointment because trying to book the appointment for it was really frustrating. The hospital only did HSGs on days of the week, but it had to be done in the first 10 days of my cycle, but not during my period so there was a very narrow window each month to have it done.
My follow appointment was 5 months after the first clinic appointment. However, I went to see the consultant privately 3 months after the initial appointment to speed things up as I knew 3 months before going to the first fertility clinic appointment we were going to need ICSI.
We then started IVF 8 months after the first appointment. If we hadn't had the private appointment this would have probably been delayed by 2 months.
I agree with bigger the delay and changing of appointments is really frustrating. There isn't much we have any control over in this process, so rescheduling appointments and endless waiting was for me just another way of feeling I had no control whatsoever over any of this. Feeling that there was some progress with treatment and that I had some control over things was one way of making things seem more manageable and allowing me to cope, and to keep having the goalposts moved was really upsetting.
I don't know if this is a helpful thing to say, but I've had 6 cycles of IVF and I found the waiting around for something to actually happen at the start one of the worst parts of the entire thing. This comment is not in any way intended as a who has it worst contest (it's crap for us all), but is to say that I am fairly well versed in this process and still found the stage you're at now one of the hardest times of the process. Please feel free to ignore that comment if it's unhelpful.
