What's up with ladies not "liking" others photos?!

Lydia • We are expecting our second child in May 2017💕My husband and I are expecting our first child a baby girl in May 2015💗
I have noticed that when we are posting pictures of ourselves they maybe over 100 views but no likes or even just a handful. For me I understand that when someone especially a pregnant woman posts a photo of themselves and feels the need to share it with us they clearly feel special in the photo, gorgeous and happy. Why not support her by not only viewing the photo but liking it as well?! I maybe alone in this and I maybe the only one who notices. If you view why not like ☺️ rant over. 😘
