we haven't told parents yet, so I thought this was funny

Okay so we haven't told my parents yet, and his parents were telling this coming weekend. We're trying to wait till after a dr appointment to tell everybody. I don't have the best relationship with my dad and really not to worried about telling him but I found this absolutely hilarious because we haven't told him yet. I send it to my brother and ask if he's seen it and he get mad because I find it funny. My brother has always been judgemental about EVERYTHING I do, if I fart and don't ask for his permission he gets mad. I wanted to wait because I don't want to get everybody's hopes up and there not be anything there. Majority of my family knows because they can't keep their mouth shut and I needed to know something from my sister in law so that's how my brother found out. Also, my brother didn't tell anybody when my sister in law was pregnant either until she posted it on Facebook. Do y'all think it's wrong that I find it funny or that we haven't told anybody yet?
