I completely understand where you are coming from. I too have feelings of guilt
that its my fault we cant get pregnant...afterall good quality embryos are going in,
But they dont want to stay in me. Its not rational but how else are we supposed to think. Lije you i havent been wrong yet & i know there is a bfn waiting for me on monday.
It is so hard to stay hopeful & positive, but try and hang in there it is not over for you by a long way just yet. Look after yourself, but more importantly be kind to yourself. Its a tough journey without beating ourselves up every 5 mins! Unfortunately we have no control over It
And we all know that mother nature is not very nice sometimes. Take care, go shopping & do something nice for you x
