Thanks everyone for your responses.

I really just started this thread as interest to hear what other people's opinions or experiences were. Seeing the only answer I have received for my miscarriage is "no apparent reason" (which I know is common), and that there was no chromosomal problem with my babies, the flights that I did so close to my miscarriage have been something I've wondered about.

Before I took those flights I wasn't worried in the slightest because, of course, many pregnant women fly. I've read a lot about not flying late in pregnancy but not so much about the effects of flying early on, particularly on implantation (though I think I may have read some of the same information that Satya referred to).

It's just something I thought I would throw up and get opinions on. It may be different for different women also? Who knows. It's all come up for me again this week because we were supposed to fly Bris to Perth and back again for a wedding and, because I'm currently in the TWW, I've honestly been too scared by it to go(based only my last experience - nothing else - I have no "science" to back it up). We've thought long and hard about it, but for me there'll be no flying during pregnany. I think I just want peace of mind on the issue. I mean, we're told to reduce caffeine etc during pregnancy and before (even though our mother's probably broke this rule and many others without having too many problems?), so I guess I just see it in a similar way of reducing yet another "potential" risk.

Thanks everyone, and I hope you all have a good day.
