Can i make a profile, but not have it approved yet?

Yes. You can make an account any time you’d like. It doesn’t need to be approved until the puppy is ready to be born. :)

Ah! Thank you!

Now, once I start the account making process, what happens then? Also, if not approved yet it won’t be marked as inactive no?

Nothing happens. You know how when you make a new character, there's that little rectangle that shows up at the top of the page that says "Submit For Approval"? Just don't click that until the puppy's birthdate. Your account will just stay inactive and nothing will happen to it, but you can work on it the whole time if you want, adding descriptions or an avatar or whatever. You just can't hit the Submit for Approval thing until the day of birth. But like, nothing bad will happen to the account in the meantime. You could leave it like that forever and nothing would happen.
