Need some advice

Hi guys! I was late on my period by 4 days. Usually my cycle is like clock work so I was pretty confused, especially with no sign of my period coming on. Well, I took a test & it was a strong positive within seconds. This was completely unexpected. I’m scared/nervous/confused/anxious. I’m waiting for the excitement to kick in, but right now I’m more in shock? My fiancé is feeling the same feelings, doubled & some. I never pictured a BFP to have this reaction from either one of us. This would be our first baby. I need some advice/stories.

Side note: I do not want to come off as ungrateful. I know there’s women that pray for this. I just need some encouraging words from woman that may be going through the same thing. Thank you guys ❤️
