I get new ideas all the time. I think the most important thing to keep in mind regarding ideas is that they’re not all equal. Some are just plain bad, some need thinking and growing, some need research (and some are good!). I personally try to be knowledgeable on the subjects I write, which means there are things I know I’ll never write about, and that’s okay.

But ideas can come at any time. I have a note on my phone that stores all the ideas I have ever had for a fanfiction. Sometimes it’s just a word or a sentence, a writing style that I’d like to try, anything really. Every time something pops up in my mind, I write it down even if it seems silly, but that way I’m sure I’ll remember it.

That way, if I ever want to write something but don’t know what, I can always refer to that note and develop plots.
