Trying to figure this out in my own so I don't feel guilty

Le-la

My husband doesn't want to know the gender, but I kinda do. So I'm doing everything in my power to figure it out on my own. Without the Dr telling me (this way I don't feel deceitful). The ultrasound tech knew this and left me on my own to go threw all the pics she just took. And let me take my own pics. Then asked if I found what I needed lol. Anyway this is a pic of baby's bladder (the only pic that may show something). This way I can never be 100% sure but have a good idea.. ohhh I'm horrible lol!! Any guesses?
