How do you deal with pregnancy envy?

I am feeling down seeing posts and people around me that are of the same age with babies and toddlers, basically children of their own. Seeing posts of pregnancy and baby toys when I have been TTC for awhile now. I have no children and been having baby fever for quite sometime now. It has been really difficult juggling being happy for them but also wanting and desiring the same for myself. How do you manage your emotions if you have ever experienced something similar to this? #ttc #pregnancyenvy #Sadness #babyfever As I am in my 30s, there's always a worry at the back of my mind that I could never bare children or it'll be too late
