My husband told his parents and brother early as I we had to miss Christmas Day as I was in hospital having tests - otherwise we were going to wait. I told my mum straight away and unfortunately she told everyone which I’m quite upset about as we have a history of recurrent miscarriage and we had decided not to tell anyone else until I was at least 15 weeks.
If you’re confident then tell whenever you want, I’m just mindful of who I would want to know if things don’t work out. It’s really difficult having to tell someone the pregnancy is ended. But if it’s someone who would be supportive and you would like to know anyway, I’d tell them.
Also, my husband’s parents were a little less than enthusiastic when we told them with our second pregnancy - they kept saying things like ‘if’ there is a baby, rather than when, and just weren’t overly excited - it was obvious they felt it was too early - they were right but it was still quite sad they weren’t happier which is something I didn’t expect and may be something to keep in mind x
