Short Protocol, Why Would That Be Then??

I got the results back from shiny new clinic. AHM 17.4 (pmol/l), the nurse said this was a good number and, based on this, they would expect a good response.
I only have her word for this as the only guide I have managed to find is their own which reads.....

<1.0 Negligible responses to ovulation drugs. Expected yields of 0-2 eggs. Most are stopped prior to egg pick up.
1.0-5.0 Reduced responses to ovulation drugs. Expected yields of 1-6 eggs (normal average=11 eggs)
>20 High responses to ovulation drugs. Risk of ovarian hyperstimulation syndrome.

We have an appt on Monday for the consent forms etc (and payment, no doubt!) I asked if I was to start down regulating on day 20 or 21, which is either Tues or Wed. The person on the phone (nurse?) said no, I'd be starting on the first day of next cycle.

I didn't question this at the time but now I'm not sure why this would be. Is a short protocol not for those who don't respond well? I've never done stims before so I don't know what to expect. The ovarian assesment was to decide the type of cycle. I'm now wondering if they think I'll have a poor response, in which case why would she say my result was good?

As much as I hate feeling out of my depth, it does look very like we will be able to cycle this month and, for that, I'm grateful. I think it will be a relief to do something, to be trying. I'm not overly confident that it'll all come together and I certainly am not taking the process as a given. I know starting a cycle is only the first hurdle.

I do feel quite at peace though. At the moment I feel we are doing the right thing. I am writing this now to remind myself it the next few weeks. I hope I can hang on to this feeling!
