Don’t know what I’m looking for ?!

I’m nearly 18 weeks and I seen so many people say they felt flutters in there stomach. I have a lot going on in my stomach but not quite sure what I’m looking for , ive seen it explained in so many different ways but I still dont know what I’m looking for 🤣 I may just wait for baby to give me a big kick and I’ll know for sure then 😂
