Which miscarriage specialist to visit?

Hi girls
I'm hoping maybe someone could help me? I'm current going through my 2nd miscarriage jn 6 months ???? it's horrible isn't it? I've not had any children yet and am worrying that there might be something wrong with me since the results of the tests after my d and c last time showed no chromosome abnormality. I have an appointment next week with dr gorgy who I have read is a fertility specialist in london. I have also read about michael dooley who seems to get very good feedback for being kind etc. I was wondering if anyone has seen either of these doctors and if so if you would mind giving me some feedback? Thank you in advance and wishing lots of luck to you all x
