Anatomy Scan but not excited...

So I'm having a gender reveal party that my step mom is throwing for is. first it was going to be just me and and husband that knew the gender. Now its just my husband because everyone keeps trying to talk me into not knowing and I have in and said fine I wont find out and be surprised.... But I don't want to do that.. I want to find out my baby's gender at the ultra sound... And now that my ultra sound is coming up its like what is the point in being excited about it I don't get to know anything.. Idk I'm probably having pregnancy emotions. I just want people to get off my back leave me alone and let me know my baby's gender lol. What should I do?
