Is it wrong of me to put up a pic of my exposed pregnant belly on my facebook page???

I am a very expressive and loving person who loves to share my happiness. I am 5 months preggers and just put up a picture of my exposed belly on my facebook account and people commented positively:) But a good friend of mine asked me why I would do that and stated that "no body wants to see my pregnant belly" and said that it was pretty disgusting. She thinks it was tacky of me to put a pictuyre with my shirt half way up for the world to see, as well as even going around telling everyone Im pregnant. I argued that I didnt see what was wrong with it, and that people love to see preggers people. Am I wrong?
