Jealous of friends

Scarlett

Little bit of background: I'm 28, I've been married for 2 years and we've been TTC for 6 months.

A friend of mine has just had her first baby and I feel dealthy jealous. I feel awful for it. I feel like she barely TTC and it just happened for her. Every month I get upset when AF arrives and another friend gets pregnant. Does anyone else feel the same?
