How early is too early to be nauseous when pregnant?

My period was 3 days late so I took a pregnancy test and it came back positive yay. My husband and I were trying for a few months for our 2nd baby, I thought it would’ve been a lot harder since I’m 36. I’ve already started feeling nauseous and I’m wondering if it’s too soon, I thought nausea started about 2 weeks after missed period? That’s how it was for my first. Anyone experienced anything similar?
