TTC and my friend didn't invite me to her shower.

AB
I'm really upset that my friend didn't invite me to her baby shower.  She knows I am ttc so I think she didn't invite me because of that.  I've been trying 5 months but I've never been nothing but supportive to her.  I was invited to the gender reveal so why not the shower.  Maybe I'm just being sensitive since AF is here and I'm depressed.
