Anyone else feel like the only one not pregnant?

Janine
So I found out I was pregnant with my first in February, but sadly miscarried and had a d&c March 29. About that same time, it seemed like everyone I knew started to announce they were pregnant. My sister-in-law just gave birth to twins. I am so happy for them and everyone else, but a part of my heart is sad that I can't have my own healthy pregnancy right now too. It's harder being on this side of 30 (I'm 32) and still not having a family of my own. 
Trying to stay positive, and God is constantly teaching me to be thankful for what I do have and not get upset about what I don't have.
Can anyone else relate?
