I'm good, right?

I got a NuvaRing sample from my doctor a little over a week ago. I just ended my period this past week and I was instructed to insert it on the first Sunday after my period. Tomorrow I'm gonna be out and about with my boyfriend all day so I was thinking I'd just insert it tonight so I won't have to worry about it tomorrow? That's fine, right? Or should I wait 🤷🏻‍♀️
