Uncontrollable sobbing

My husband told me he had to work and might not make it to our 2nd sono to find out the sex. I was super quiet and then... I flipped out. I told him I didnt want to open some envelope with him and what if I went and there was no heartbeat. All of this with so many tears and snot. I can laugh now bc everything is great and we found out we're having a little girl🎀 but have any of you gone off the radar crazy on your significant other? I've NEVER behaved like this before in my life. But in my defense, what the hell was he thinking?!? This our first baby.
