Movements at 15 weeks

This is my first pregnancy and I'm 15 weeks tomorrow. I've felt what kind of feels like gas bubbles (but not) for a few weeks but today I feel much "stronger" spasms and the same bubbly feeling. Is it possible to be feeling movements this early? I'm a pretty small build so I'm not sure if that has anything to do with it?
