What about st mary's? They're the most well known.
I went to st mary's privately after being disappointed at king's - poor communication, felt dismissed, was obvious that they wouldn't do the more expensive tests (eg hsg) that were standard at st mary's. Not a specialist recurrent m/c clinic.
Thanks for the update Dozer, I have had my first appointment with Raj Rai privately, I was quite impressed. Waiting for tests and ultra sound but he did suggest progesterone to me. He also looked at some basic tests my GP had done and said my thyroid might be an issue (its in the normal range but high end of normal) So looks to me like my issue is hormonal, but lets see!
