Question about babies movements?

Ok so I am 19wks and 5days and I haven't really felt any movement. I think I feel fluttering every once in awhile but idk if that's just gas or if it's actually movement. Also when will I be able to feel actual kicks, like where others can feel it too? I'm just hoping that there's nothing seriously wrong with the baby and that it's just because it's my first pregnancy. Thank you in advance for all your answers.
