PAIF response here.
Part of our situation came as the aftermath of Hubby having illness and surgeries, which inevitably would affect our fertility. So family knew. The advanced endo that blocked the tubes---well, that was the game changer from IUI to IVF.
All of our family and friends knew. I'm an open book kind of gal, and I was amazed at how many other women out there also struggle. By talking about it, others seemed comfortable talking to me about it, and we were able to support each other. Or---by talking about it, others would say, "Oh, we did IVF for ----insert child's name here---." Then they'd share their stories/journey with me, and I found it comforting....or comforted by the fact that I knew I had another gal in my corner to give me a shot if I got in a pinch!
I didn't worry about others feeling sorry for me. I appreciated their thoughts and prayers. I also didn't mind talking with people about it b/c mentally and emotionally it has been such an all-consuming journey, that it felt good to talk out loud about it.
