Am I wrong ?

Four years ago my Bestfriend was told she was getting a girl and then when she went into labor she got a boy! So I do understand her to some extent.

At my anatomy scan I was told I’m getting a girl which is what I’m going with, I’m actually pretty confident with what the doctor told me! My Bestfriend on the other is going down die hard I’m not getting a girl, everyday she’s telling me my baby is not a girl which is getting on my nerves, she’s telling some of our friends my baby isn’t a girl and for my sake she hopes I get my girl. At this point she’s ruining everything, my mom was throwing a surprise baby shower for me which she has ruined at this point, she went telling them not to do the decor in pink, use gender neutral colours, they asked me for my baby registry and the stuff I had in my registry I found out she’s trying to change the pink stuff to other colours at this point I’m just so frustrated! She told me she won’t be buying me anything pink or girly and I told her that’s fine, anything anyone gives me will be extra, my husband and I already decided we were providing everything we needed for our baby so anything anyone gives us is just that. She said just enjoy the moment and let everyone continue guessing if it’s a boy or girl until birth. It’s like I can’t enjoy this moment, I already have a hard pregnancy, I’m constantly sick on top of all the other pregnancy symptoms, had to stop working, the list goes on.. honestly either boy or girl I would be happy and I’ve waited weeks to find out what I was having and now I just want to enjoy the moment.

I’m at the point where I just want to tell her off, but I’m not sure if I’m overreacting or not.
