Hello and welcome,
I think it is a tough call whether to tell people or not. DH and i were very excited that at last we were 'ready' to have a baby. At first we told close family and friends who of course told there close family and friends. I told some people at work and then before i knew it 12 months had past and we were still ttc. Ttc with alot of people asking how it was going. It was hard to deal with at first, feeling inadequate because it had not happened yet. After 3 years i think everyone in our lives knows we are ttc and have stopped asking questions. We are now facing the dilemma of 'who to tell we are going through IVF?'
The hardest thing for me was dealing with the dissapointment over and over but talking about it helped. Tough call, best of luck with the decision.
