Can anyone relate?

Yesterday I got my first bfp. I’m retesting in a couple days since the line was faint but clearly visible. Is it normal to be this nervous? My fiancé and I are so excited but I can’t help but have this panic in the back of my mind. Like what if something goes wrong? I always think of the worst case scenario with most situations 😞 I just want the feeling to go away so I can focus on the exciting new chapter of our lives
