My Sister in law vs everyone else....

I'm almost 28 weeks (we're not finding out baby's gender until his/her birthday) but for some reason, literally everyone thinks I'm having a girl. Except for my sister in law. And my husband (obviously all men want a boy.. especially when it's our first lol) I'm 99.999% positive that the only reason she wants me to have a boy so bad is because she wants to have the first girl on her side of the family.. why do I say that? Because I've heard her whispering it to other people before.. "she can't have a girl before me, I need to have the first girl". She's definitely the jealous/greedy type. But anyway... she's trying to find any and every way to justify the fact that my baby is a boy.. she told me a few weeks ago that I look like I'm carrying wayyyyyyyy lower than she ever did when she was pregnant with her son. So I put pictures of our bumps side by side, and I had to share because it made me laugh. Im in the orange, sister in law is in the stripes. I know it's just a wives tale that boys carry low and girls carry high. But I'm definitely carrying higher than her lol (sidenote.. it really doesn't matter to me what baby is, as long as he/she is healthy and stays put as long as he/she is supposed to lol BUT, I would get a kick out of having a girl just to tick her off because of the way she's reacting.. is that wrong of me? 😂)
