Taking Prenatals

I ate around 6:30pm & forgot to take my prenatal pill.. right now at 9, surprisingly, I'm not very hungry because I've been having little snacks, but I was wondering if I could take my prenatal without any food, or if I can with a small snack. I know it's recommended to take with a meal, but I guess my question is what are the side affects of taking it with no food.. Nauseous ect...
