Sister pranked me at my gender reveal. Am I wrong for being upset?

Y’all tell me if I’m being ridiculous or hormonal for being upset over this. I’m pregnant with my 4th baby. I’ve only had 1 gender reveal it was with my first baby and didn’t get to do one with my next 2. This is probably my last baby so I wanted to do one this time since I regretted not doing one with my last 2. I asked my sister if she wanted to be the gender keeper for this pregnancy since I trusted her to do it but I made it clear I did NOT want to be pranked. She agreed and was all on board. The day of the reveal I was already so nervous, I didn’t really have a preference I’d have been thrilled with either gender but did say I would be super excited to have another girl since I have more boys than girls my only daughter doesn’t have a sister and I’d be happy if she got one since I’m not planning on having anymore kids. I wanted the reveal to be recorded for memories and to announce it on my social medias send to family members etc. the reveal was being done with confetti shooters. The video starts and I get all my kids in the video and pop the shooter with them, pink confetti comes out and I was sooo excited. The video is still going and she pulls out another confetti shooter herself and pops it- blue comes out. So then I’m just standing there like wtf and already getting kinda upset because at this point I realize she’s pranking me. She then pulls out a 3rd confetti shooter and hands it to me saying this one is the real gender. Like I said at this point I’m already annoyed so I feel like my reaction is ruined no matter what the gender is gonna be. I pop the third one and blue comes out she shouts it’s a boy but I just stood there and looked upset NOT because it was a boy, but upset because I was pranked and was told it was a girl first. I literally would have been thrilled if the first one I popped was blue but now watching the video it looks like I was disappointed about having a boy when I wasn’t I was just mad that she pranked me and said it was a girl first it pretty much ruined the video I cropped my reaction out before I even sent it to other family members or posted it because I didn’t seem happy when the blue came out. I just cannot believe she pranked me knowing I didn’t want her to do that to me. This was probably my last gender reveal I’ll ever get to have and I feel like it was ruined for me
