I can imagine how you must be feeling hurt right now. Listen petal have you read Dr Beer's book 'Is your body baby friendly'. If not then get it and read it from cover to cover. iMHO it pretty much covers why things could not be working for ladies ttcing. I felt megga hopeless then got that book and had hope my problems could be sorted. Read it and go from there.
I wish you well Dee. its hard when doctors don't seem optimistic but you only need one embryo to stick and you are on your way. Don't look back honey bc you are not going that way, best, THK
