Everyone but me

I've been upset for a while now because it's as though everywhere I turn, someone is pregnant and they haven't even been trying. My friend has a baby who's almost one and she was told she can't have kids and her boyfriend had already had a vasectomy yet they have a baby who's almost one and she was thinking of putting he/she up for adoption so he/she could have a better life than they could provide. It's very frustrating when we've been trying and have tried multiple different things. I'm tempted to go to the doctor and ask if I can even have kids but I'm afraid of the answer :(
