Feeling very frustrated and awful about it...

I've only been married a few months but my husband and I have been TTC for about a year now and it's just not happening. I had a miscarriage recently (on his birthday of all days) and I swear everyone around me is pregnant! 4 of my friends and 3 of my husbands friend's wives! I'm still happy for them of course but I'm finding it so hard to not hate myself for not being pregnant too and I feel like I'm letting my husband down because he wants a baby just as much as I do. Am I a total jerk for feeling this way? Or do other fellow TTC ladies ever experience this? :(
