Crazy Pregnant B****

Okay so I need some honest advice on a situation as there’s a chance I’m overreacting since I’m 5 months pregnant! So I have had the same group of best friends for over the past 7 years. There are 5 of us, with three of us married. Well recently I just found out that all of my friends are in our other friends wedding expect for me. I found out because they all secretly went dress shopping, didn’t say a word to me, then when we were at dinner they were non stop talking about dress shopping, who they would walk with, etc etc. so obviously I was a little surprised seeing as we’ve all had each other in our own weddings. So of course I don’t say anything and they continue on, with the one friend who is getting married says “it’s awkward because we have 9 guys and only 8 girls” so clearly I’m like...

I still didn’t say anything. But I waited until we all left and texted one of my friends who is in the wedding and I asked if I did something wrong to be the only one not included. And she says something along the lines of “we knew this was going to come up, she just wanted other friends in the wedding too... she doesn’t want this to ruin your friendship” blah blah

So I’m sitting here like, welll I’m hurt, but why wouldn’t she let me know that I wasn’t in before dinner then, is that too much to ask??! And at this point she hasn’t said one word to me about not being in it.

So I would obviously never do anything to ruin her big day, but do I have a right to be upset about this, or am I completely overreacting?
