Wanting a baby but How do you know your ready?

I am just curious about how you all decided you were ready to have your first? I'm an anxious person and I tend to stress about thinks that are out of my control. My husband and I have decided we want to try for our first! While I am thrilled I have concerns, he is a student (will graduate with an engineering degree next April) I am a nurse and do quite well but work two jobs. Currently money isn't an issue for us. I have concerns about relying solely on ei for a couple months while he finds work though. I am saving so we can buy our second home as we will be relocating when he finishes. We are both 29 and I'm not sure how much longer I realistically want to wait. We feel ready. I guess I'm just looking for reassurance, did you all have concerns when trying? Or are we rushing things.
