Second baby anxiety

My husband and I know that we want another kiddo. We planned to start trying this summer (originally June but now July) last fall but every time we get close I start second guessing it. I felt like this with our first and we planned her. Will I always feel like this? I think maybe it’s just such a big decision that I want it to be perfectly timed...I wish it would just be an accident but I’m too in tune with my body. Someone tell me that it’s okay to be nervous about creating an entire new human again 😂

(I am excited about it though so don’t get me wrong!)
