Feeling movement

Sadie

Is it normal to feel movement at 18 weeks? I am 18 weeks and 4 days with my first. Every now and then a couple times a day, I feel just like a little “pop”, they other night I felt 3 “pops” about 10 seconds apart, is that hiccups? I feel like I’m too early? I feel like it’s not gas because I don’t pass gas when I feel the movement. I’m new to this 🤷🏼‍♀️
