Thanks Ladylove. I am definitely going to start taking the EPO, can't hurt.
I don't really know what might cause hostile CM, and maybe that's not really what I have. I do get EWCM, so maybe it has anti-sperm antibodies in it or something that are killing or blocking the sperm. My FS said they used to do a post-coital CM test, but that the results weren't useful, so now they just do IUI. It's just weird that we have had a lot of trouble conceiving naturally, but not really any trouble at all with ovulation induction and IUI. Am thinking of trying the ov induction drugs and then timed intercourse. Don't know, it's all so confusing.
Thanks for your reply
