Am I going crazy?!

Long story short, after being diagnosed with PCOS and many many failed fertlility tratments, I accepted the fact that having a child of my own was just not in the cards for me 😔. I grieved and made my peace with God and moved on..however recently I have been browing baby items online, leisurely strolling into maternity clothing stores, I've gone so far as to purchasing newborns clothing 🙁. Knowing full well I will never need any of these items, I'm finding it rather hard to control my actions. What gives?! Why is this happening now?! Just needed to get this out as I am too embarrassed to talk with any of my family members.
