My best friend is begging to share my scan pics (on snapchat/instagram) and I don’t know whether to allow her to or not.

My pregnancy isn’t a secret but I haven’t announced it to anyone other than close friends and family, I personally don’t wanna share the news on social media till at least my gender scan but that’s just because I don’t want all the attention 😅

I just can’t figure out my friends motives for it, she says it’s cos she’s excited but what has she got to gain from sharing my scan? Am I being weird? I know it’s my choice either way but I just can’t understand why she wants to and what I should feel about it...I’m just very like hmmm🤔
