Should I share my news?

Need advice: my husband, toddler and I are on our way to a weekend vacation with some friends of ours who live in a different state. I’m about 7 weeks pregnant, and after two tough MCs in the last year I am really not ready to share the news. I’m also sensitive to the fact that my friend (who also has a two year old) had to have a hysterectomy after her first baby due to complications ... and I don’t want our happy news to cast a cloud over her holiday.

The added issue is that I had a bit of bleeding earlier in the week (everything seems fine thank goodness, but it really freaked me out given my history) and my doctor told me to take it as easy as possible on this trip - not a lot of walking, etc. And obviously I won’t be drinking! I’m normally very active and love to walk around, and enjoy a nice glass of wine or two so I’ll have to explain away some of these changes.

Is there ANY way at all not to have to share my pregnancy news given these circumstances? Or should I just go ahead and tell her/them I’m expecting? I hate to make it a “thing” but I’m thinking it might be unavoidable. Help!
