How to know when it’s real labor?

Lo

Hi guys! I’ve been getting frequent contractions (between 2-5 minutes apart), but they’re not totally terrible where I can’t breathe. With my first, I was induced, so I have no clue what to be looking for/expecting other than contractions 5 minutes apart for an hour or two? Any other ways of knowing besides water breaking? It’s so confusing lol.

I’m close to 37 weeks. 🤰🏼
