Am I being selfish?

Michelle • Soon to be mommy of 3, yikes. I think I'm too old for this 😢
A lot of ppl are asking me post my belly bump on social media and I'm not comfortable with it. I'm really insecure about my body before I was pregnant and now that I am it makes me feel extremely weird and insecure about it.  Is something wrong with me because I don't want to post or share pictures like that?
