I've used it post-miscarriage and also to help bring labour on. In the first instance, I found it really helped me sort out my emotions etc (it was 2 weeks before my wedding) and 'cleared' me physically from it IMO.
One year on, I was needing help bringing on labour (as I wanted to avoid being induced). While it didn't actually start it, I was in labour within 10 mins of induction starting, rather than having to patrol hospital corridors for hours on end. Another in my NCT group had exactly the same experience.
So while it's not a direct answer to your question, I would really recommend giving it a go - there's certainly nothing to lose, and in both my situations I've found that it helped.
The first time I saw Judi at the Awareness Centre, who was lovely and specialises in fertility etc.

The second time I went to Tom Ings (equally lovely) in Balham, as did my NCT friend -

Good luck!
