I should be happier... Why the tears?

I've been married for a year and three of my six bridesmaids have already had a baby. I am so happy and so jealous of them at the same time. All of them on baby #2. I want a baby so bad and I just have these mixes of emotions right now. I'm over the moon ecstatic for my friend who told me today yet some tears were shed too once we hung up the phone. I really really need baby dust. Having a tough time lately... You ladies are the only people in my life going through the same emotions as me. I have a friend who has had struggles in the past but thankfully she has had good IVF luck and is due #2 and 3    I don't talk about this much and I hope I don't sound like I'm complaining.
