Movement inconsistent?

I’m due towards the end of the month and therefore only about 14 weeks. About a week ago, I DEFINITELY felt baby gently rolling around. It wasn’t flutters or “popcorn”, more of a rolling. It happened a few different days and surprised me because I didn’t feel my first until about 20 weeks. However, since then, I haven’t felt any of the same movement. It’s been at least 3 days without any obvious movement. Is it normal for movement to be this inconsistent this early? Or have moms who felt movement this early, felt it pretty consistently? A little nervous. 😕
