Baby movement!

Courtney

So this is my first pregnancy and I am clueless about what I am feeling with my body. I am 18 +1 and I’ll feel a knot in my stomach that will last for about 6/7 seconds then go away. It’s not a kick, jab, flutter, popping, none of the things I read is movement. It’s just a knot. It feels different from round ligament pain as pain isn’t associated with the knot. It’s not a permanent or stationary knot so I’m not really worried. I’m just curious if I could be feeling movement and just unaware that THAT is what it is.
