@Sunandshowers - yes totally! I think you just notice it more when you're TTC and obviously it bother you more then too. When I lost my first to MMC, literally EVERYONE I saw or heard about was pregnant and I'm ashamed to say I had a VERY hard time dealing with it, as it just seemed very unfair. Then when I got pregnant with what is now my DC (currently sat on floor, 17 months, watching Peppa Pig!), I didn't really notice anyone getting pregnant, even though of course they were!
It is the same now. Unfortunately my room mate at work is a little insensitive (she's only 23 though so I forgive her), as she knows I'm TTC and struggling and she keeps banging on about X, Y, Z person is pregnant, seems like every day!
What I would say, is that whilst it's hard not to be jealous (2 of my team mates are going off in next few months to have their 2nd and 3rd!), you never know what struggles they themselves have had privately. Just after I had lost my first, I bumped into a guy I know whose wife had just had their first. I was obviously very nice about it to him and congratulated him, but when I walked away I was crying and thinking "it's ok for them, they've got a baby, life is easy for them". A few weeks later a mutual friend mentioned them and said how great it was they had finally had a baby - turns out they had been pregnant twice before and had lost both. So it does happen really easily for some (and they will never understand the pain of being unable to conceive or losing a baby) but for more than you think, the road is not easy.
Sorry, long post, guess I'm just saying hang in there - it is something that a whole lot of people do struggle with, they just don't necessarily talk about it x
