Am I being too anxious?

My husband and I had tried for 3 years before we finally have conceived. I’m 5 weeks & 3 days. My hubby is so excited he tore apart our guest bedroom to turn it into our nursery. Literally tore up the carpet to lay hardwood, tore apart the closet shelves. I feel like it’s too soon. We’ve tried for so long I feel like everything is too good to be true.. I know I’m not alone but I worry it’s just in my dna

I just don’t know how to feel my first ultrasound isn’t until the 24
