Pregnancy jealousy?

Jenna • Due early February with my rainbow baby ♡
I had a miscarriage on Friday and I just found out my coworker is pregnant and due around the same time I was supposed to be due. When she told me I got so sad but I covered it up. I hate that I feel this way, but I just miss my little growing baby and the fact that she is fine makes me so sad and jealous. Anyone else feel this way?
