To talk or not to talk, that is the question.

You know, this is a hard subject because, for those of us who don't get preggy at the drop of a hat, it can feel very much like an interrogation month after month, insult heaped upon injury. On the other hand, when we do tell, not the world in general, but 1 or 2 that we really trust, we do have someone to vent to, someone to hold our hand and be our cheerleaders, and someone who's shoulder we can cry on if something doesn't go as planned.
With my 1st pregnancy I told almost everyone as I was really excited. Had a miscarriage about 2 weeks after I got the good news. It was very upsetting to say the least, but I couldn't imagine having to go around as if nothing had happened because no one knew. Yes, it was hard at first to talk about, but then I came to the realization that although it was sad, it was a part of life. I ended up having a successful pregnancy after that, and everyone was overjoyed for me. It more than made up for the pain of before.
Since then I have had 1 more MC and 1 full term, and I still hold true to the rule of letting the ones you trust know, and let everyone else figure it out when you are ready!
Even though it takes time, trying should be fun. If you can't share the joy, or get uplifted by those who care, you could open yourself up to a lot more stress and feelings of alienation than necessary. Hope springs eternal!
