I told my family but as time went on I wished I hadn't. I had hoped for support, and I suppose in the first few cycles, I did get it, but as time went on and success eluded me, things changed. They began becoming uncomfortable around me, esp since my sister fell pg 'accidentally' during my second cycle. I was treated like a pariah for a while, and as more failed cycles piled up, the pressure began from my parents for us to give up. I won't go into too much detail as to how difficult it was, but if I were to ever go back to IVF, I wouldn't be telling my family.

This is my own personal experience though, and probably one end of the extreme, but it's honestly not a bad idea to be discreet about who you tell.
