Revealing the sex to your SO, ideas?!

I got the results of my DNA Harmony test today at work. Everything's good (whew!) and we're having a girl! Now I'm torn on how to break the news of the sex to my husband. I told him we were pregnant over Snapchat (haha!) so considered that, but also thinking maybe I could work it into Father's Day on Sunday. If I can keep it in that long! Any ideas?! How did you tell your SO if you found out first?
