Social media

I didn’t even announce to mom I was pregnant until I was 13 weeks. So obviously I haven’t posted on social media. A huge part of me doesn’t want to. I just want to announce once my little girl gets here, however, I see everyone else announcing and I just want to be like “me too”. Anyway, is anyone else considering not putting their pregnancy on social media? Because nobody understands my not wanting to. I’m a private person in general, so it just makes sense to me.
