Is it weird?

🦇𝓡
So I don't really talk about being pregnant on my social media. I haven't shared ultrasound pictures or anything. The only "pregnancy posts" I've made were of me being sick and puking all the time. I don't really plan on "announcing" or anything. I quite enjoy just having family and close friends know, but I also feel like that's weird because I'm probably going to post pictures of my son when he's born and people are going to be wondering where this baby came from. I feel like I'm going to get bombarded with questions and comments and all that crap. I already know I'm going to be annoyed by it, but I'm not sure how to avoid that... Any suggestions?
