Nervous/scares yet excited? In my head!

So weird.... Hubby and I had a what you could say “great weekend” due to colder temps and snuggling inside all weekend.... we aren’t TTC right now but aren’t using protection except last second withdrawal. as I look at my calendar I can’t help but get a little excited for when my next period comes or don’t comes? Why do I feel this way? I feel like If we didn’t want to TTC then I would be like no way

but I’m kind of excited? Does this mean I am ready for a little baby? I wonder if there is a good chance of a little baby coming soon? Why am I in my head so much?!!!
