Feeling sad and torn.. find out or not??

So I’m expecting my third baby and I’m due in may. We decided not to find out the gender since we have one daughter and one son already! But we let our moms find out so they could get some of the shopping done for clothes since I didn’t really save any of the kids and I didn’t want all gender neutral.

Well, at first there was two references to baby being a girl, nothing that would really make me thing it was a girl 100%..... but fast forward to now. My nurse at my last apt asked if I was having a boy... My mom wanted me to pick new coming home home outfits bc the one I needed was sold out. Went on the site to pick new ones and on the main screen it shows what’s sold out and needless to say the boy one was ... my mom said both had previously been sold out. And today my mother In law called baby a him twice.

Now I’m so confused if I should just open the envelope and find out with my husband or keep waiting until birth. I’m so sad bc I’m pretty positive it’s a boy with as many slip ups. My mother in law tried to cover it afterwords and say “it” but it was too late.

What would y’all do???
