I need to vent...

Today I found out one of my best friends is expecting her second child. I'm more than over joyed for her, she had her first baby a little over a year ago and just got married a little over a week ago to her Prince Charming! I couldn't be more happier for her....but it also hurts because I've almost been married a year and me and my husband have been trying since December of 2015 to have our first one. I feel horrible that I cried for almost 10 mins because I haven't got that + yet, we've been doing everything right but still nothing...I feel conflicted, I want to have a conversation with her about more with this baby, but I just can't because it hurts...I feel like the worst friend ever...any advice?
