When does it feel real?

Last year around this time I had a miscarriage. This year I’m coming up on being 12 weeks with my rainbow baby. It still doesn’t feel real though. We had a scare around five weeks up until 11 where we weren’t sure baby was going to stick. I just got the all clear that baby looks great. I still haven’t convinced myself that I’m pregnant though. It doesn’t feel real to the point that almost nobody even knows and I don’t have plans on telling anyone yet. Anyone else experience this? When did it feel “real” for you? How or when did you end up telling people?
