Is it hard for anyone else to believe they are pregnant?

Like, I took a digital test that said pregnant. And 2 other positive tests. But for some reason I don’t “feel” pregnant. I mean physically I do, definitely! But emotionally I’m just worried I guess? Like I want to tell the world, I want to start shopping and buying all of the things. Lol. But maybe it’s because I don’t know the gender yet? Maybe I’ll be more excited when I can start buying stuff. :) we have 2 boys already and we’re hopping for a girl! We have been trying for almost a year and now that it’s finally here, I feel like it’s a different type of waiting game! Does that make any sense at all..?
