positive beta hcg, doubling nicely, but still can't believe it!

I've taken two beta hcg blood tests. And today my doc confirmed that I'm pregnant. But I still can't bring myself to believe I am.  It's been a bit of a journey and for some reason I just feel like it's too good to be true. And if I tell my close family, or change my Glow status or update my other fertility apps something bad is going to happen. Like putting it out into the universe will jinx it! I got the news earlier today but I'm still apprehensive about even telling my husband! what if my period shows up tomorrow or the next day?
