Privacy violated on FB

Melanie • Mommy of three... Soon to be four! Still in shock but super excited and blessed to be on this journey of pregnancy again
Today I was very upset to see a post on FB my (cousin in law) posted and tagged me in. Mind you; I have I not officially announced our great news on FB.. I am 5 months but wanted a belly and my kids to be in our announcement pics. 
Today I see a tag/post with a post on an article that reads "I was totally ashamed and embarrassed about of fourth pregnancy"  and my CILaw felt the need to say "see Mel there's no shame in a fourth pregnancy, hahaha" 
It made me so upset that she would even post something so condescending and negative on a beautiful time in our lives. I immediately called and told her that it was a little rude and that I didn't appreciate that kind of publicity about our fourth child. She turned it around on me and said she was "DONE with the conversation and hung up on me"
Needless to say I was dumbfounded. 
How would you all feel about this???
