N2L lovely lady, I posted a question on belly just before, but is there a place for me to post where I can chat to people with secondary infertility? Basically I want to chat to women who have a child or children but are unable to add to their families.
If there's a group for that, I'd be interested in joining.

As for your questions, most FS are fine with you using the low-dose aspirin, but I always recommend discussing it with your FS first. For most people there's no risk of harm, but for a small portion of the population there can be bad consequences. As for the hypnotherapist/etc, if you found it helpful in the past and it will make you feel better now, then I say go for it!

Emma, I can't see why you wouldn't be able to do PGD with an antagonist cycle, but I've never done PGD, so don't know what the requirements are. I'll be interested to hear what responses you get from those who have done PGD before.
