Coconut - sorry to hear of your losses. Your thread headline hit me as I could have written it myself (well in a month's time).
Am 43 at the end of next month, and have had 3MMCs since August 2009. All around the 10-12 weeks mark. Like you I get pg very quickly. I have one DS born when I was 40.
After my last MMC and ERPC in August 2010, I "qualified" for NHS RMC care, but also decided to explore private route.
In short all tests have come back normal, so it is a case of "old eggs" or bad luck, but both the private clinic consultant and NHS chap I saw today were not at all dismissive about my age. Of course we discussed it as a factor, but both encouraged me to try again. (Actually I have been trying for the last 3 months, no BFP yet, the longest I've ever tried without conceiving 
)
I posted this on the 40+ TTC thread earlier - we're a lovely bunch over there, pop in and say hi if you want some handholding and support?

Had a really positive appt this morning at the recurrent MC clinic. The consultant was lovely.
Basically if I get pg again, I will get scans at 6/8/10/12 weeks, and immediately I will be under his care.
He reiterated what I'd already learned at the private clinic and was appropriately empathetic to my situation.
I didn't want or expect a "it'll all be ok" type chat, it was just really reassuring that I would get lots of handholding and support next time round.
Even with 43 looming next month, and after 3 MCs, with the all-clear results I have had, there is a 60% chance of another pg NOT ending in MC. (In fact he said slightly higher as I already have a child).
What we did talk about (raised by me) was the tough journey of pregnancy of women of our age... as in harder to get pg, more likely to MC, higher risk of chromosomal abnormality etc. I guess I wanted him to know that I was realistic about the chances of having another child, and although I am/will try again, I'm doing it with a more balanced approach.
I feel in quite a good place.
