Getting a little annoyed with people's gender assumptions

So I'm 21w4d; my SO is currently on his way back to base from his 4 month deployment to Europe. I'll finally be seeing him for this weekend in which we will finally be having our reveal party ! So keep in mind I do not know the gender... But I'm getting a little sick of everyone's comments on the gender. I'm happy with a boy or girl don't get me wrong, I'll love the baby regardless. But literally everyone's telling me to start picking boys names out, and shop for a boy. Why on earth would I do that if i don't even know the gender yet?! Everyone keeps judging on my bump and my bump only, because I'm carrying a bit low. However I do have along torso so that could be a reason why I'm carrying low. Some keep saying also since I got pregnant right before ovulating and after doing it 2-3 times it's got to be a boy because 'boy sperm is faster'. My line thats forming on my tummy is also straight but slightly crooked so people are saying boy. People also say since I'm 1 of 6girls(sisters) and 1 boy(brother) I'll have boys. As of right now I just don't want to know until the reveal but everyone's plugging into my head that it's a boy and it's kind of getting me aggravated. I see girls carrying low all the time and have girls.. Here's some clips of my line and tummy and all. I've had most wive tale symptoms of girl. Has anyone else experienced this??
