I have to see my dad soon and im hiding this pregnancy from him for as long as I can lol. Please no judgment, I'm doing this this a reason. Can anyone help me out?

This is what I'm working with I'm 20 weeks

Update* so I just got home from seeing my dad. It wasn't bad at all, i didn't even try to hide it. I wore a tank top with some shorts. My dad is a bigger guy (almost 600lbs if not already there) so he just thinks I've just put on weight (which I have). If he did notice I think he just didn't wanna ask. He isn't a shy person, though and has asked me years ago if I was pregnant (I wasn't) and just let it go when I said no. I have to see him next week to visit my grandma who isn't doing well. I'll be 21 weeks then. I'll try to actually hide it then, as I'll be with him for over 6 hours in the car. Thank you all for the advice and for being so kind. I appreciate it so much.
