Gender Scan?


So I keep hearing you get the gender scan around 20 weeks. I am hoping this is true in my case and we will know. I am a bit anxious as I am 13 weeks and 5days pregant... That would put my scan at about a week or two before my birthday... Give or take based on how my doctor is spacing my appointments. I was wondering.. I will be turning 30 this year.. Not so exciting... Would it be wrong to instead of trying for a birthday party use my birthday as a gender reveal date? We wanted to do one but I wasnt sure if doing it on my birthday is a good idea. I just thought it might take the down er out of the whole "youre getting old" jokes people tend to make at thos milestone birthday.
