ugh, i am so sorry!! It could be a number of things, and the dr.s may never have an answer, it could be a combo of a bunch of things. I have a friend that has had 7 miscarriages in 8 years. all i can suggest is to be there for her, for
those of us who have infertility issues, little things can be annoying. Like the baby aisle in target, evry pregnant person you come in contact with, etc. just becuase its a constant reminder that you cant have a baby. so, sometimes we just need someone
to listen, and not bring up baby stuff (((hug)) for your friend
