2nd baby...already feel the worry

I have a 2 year old daughter, no family history of miscarriage, no previous miscarriages- yet I am sooo worried.

We have been trying since January (I have short cycles, so it was over 10 cycles) I remember feeling this way with my first, but it was all new to me. I figured I would feel more confident with baby #2.

I tried making my appointment, but a nurse has to get in touch with me to do it.

Just pregnancy nerves? Any tips, stories, experiences, etc.

Thank you all!
