Am I over reacting? Gender Reveal

Jill • Happily married, had my first son 12/31/16 (conceived via IVF), ready to expand my family!
So my hubby had to do <a href="https://glowing.com/glow-fertility-program">IVF</a> to get pregnant after a long road of infertility. Our family and close friends all knew what we were going through so when we told them we were pregnant they were excited but didn't have the shock factor i had been dreaming about when annoucing I was pregnant. But I knew that we would have a small gender reveal which we thought we could make up for it. Well my parents, who I am close with, decide right after we got pregnant to take a European vacation. They happen to be leaving right when we would want to have a gender reveal, meaning I would have to delay the reveal by two weeks until they return. I was pretty bummed initially because we are so exicted and can't wait to find out the gender. Well today my mom called and told me they were going to extend their trip a couple of days so they could be there at the same time as my aunt and uncle. For some reason this hit a nerve, I am already waiting graciously for them to get home and now they want to delay it even more. Just hurts my feelings... I really didn't hold back with my mom about how that made me feel. Just wish they hadn't rushed to plan this trip... I know it's not that big of a deal and I will get over it. I just wanted the gender reveal to be special, and it wouldn't be without them there! I know it's a silly problem, and I shouldn't be upset but I am. Would this bother you?
