Ditto for me, I find it really hard to hear too, especially when it appears to be so easy (and cheap!) for them to conceive. I think it's entirely normal, and to be honest it doesn't go away, even after I had my son I felt like it was so hard when I heard friends and family were pregnant, but I realised I was often directing my anger at my infertility at people who weren't responsible for it. Christmas is a tough time which adds to the emotions too. Try not too work yourself up too much and enjoy what you can
