petty or not?

There have been like 4 pregnancy announcements in the last few weeks on my FB feed. A bunch of other girls are further along in their  pregnancies,  and here I am looking like the girl that got stood up at prom. Is it petty of me to want to unfollow their feeds so I don't have to see their posts? One girl posts a different photo from her announcement shoot every other day and talks about "how shocked" they are because they "weren't trying and just enjoying being married".  She is dragging that shit out!! Am I crazy? Have you unfollowed someone's pregnancy posts?
