How should i handle this situation ?

Visiting this weekend some relatives and they always ask me and my husband about babies and pregnancy.

I’m 7weeks and don’t wish to tell anybody that am pregnant until second trimester.Don’t wanna also to respond with “ No im not pregnant “ ( don’t find it very healthy to say as i had a mc before ) But don’t want either to tell that i am.

It’s frustrating and we MUST go. Any ideas how to answer the question “ are you pregnant “ or “ when you’ll think to conceive. a baby “ ?
