Thank you for the info juniper76. Yes it must have been HSG because I did have the dye. I am pretty sure I already had laparoscopy with it aswell because they did find a little bit of endo at the time. This was in Dec 2008 so maybe it's a good thing for me to have again.

They have said I don't have the killer cells or immune issues. There is some problem with implantation but its got me stumped!
