I'm sorry. I hope your time comes soon! People don't always think before they speak. TTC can be such a sensitive issue especially when you add infertility into the mix.
I didn't share that I was ttcing until after our 2 failed ivf. By then, people at work were worried since I had been missing a lot of work. Thankfully they respected my situation and didn't ask after my ivf cycles that followed. I did have a friend spread the word for me. It was easier for me to handle the situation by not sharing.

Good luck this cycle.
