Rene: Sounds like you have a paternalistic/interventionist gynae - works for some women, but I prefer a different kind. The basic philosophy of some gynaes is - don't read too much, don't ask too much, don't listen to contrary advice in books (because they relate to Caucasian populations) - "Just Trust Me".
So far, most of the internet sites (the medical ones, and the textbook studies/ academic articles, not the forums) have been reasonably accurate when I asked my gynae to clarify.
Must of course learn to differentiate between the nonsense that's out there (and you're right, there's a lot of nonsense out there) and the good stuff.
My gynae loves to discuss studies and research, even with us non-medically-trained ones. We discuss the latest studies, the pros and cons, the different theories, then he lets me make a decision. That has always been the case - since first preg, to m/c until now.
But I know that doesn't work for everyone. To each her own.
It may seem like over-analyzing and you are probably right. But when you've had a M/C in the past, you sometimes cannot help it. While you know that worry is not going to help matters, you want to be prepared - so that you ask the right questions, you are armed with the relevant info if the need arises. Because with a M/C you lose hope and you lose control. If reading up and knowing what the science is about helps us cope a bit better, I see no harm.
