My parents also need to cope with my infertility.

I am now thinking with a more rational head.  It has really struck me now that this could seriously affect my parents.  In a few weeks when my sister's announcement is made public, my mum will tell my extended family.  Even though this must be so exciting for her to at last be a granny, I am sure she will be met with comments that it is my younger sister and not me who is pregnant.  I hope for her sake that she can deal with that calmly. This just proves how deeply infertility cam affect a family, and not just the patient directly.
