Baby names

Kristen • Married in September. I have a 3 year old and me and my husband are having our first together but yet he treats him good
I'm only 4 weeks 6 days pregnant and i have downloaded every <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> possible from tracking how far along I am to baby names and check lists...is that too much or is it normal to be that excited?
