Normally for 1st preg, u won’t feel the kicks so fast. Sometime u feel movement but not kicks. It may be gentle like bubbling feeling, or for me, like popcorn popping in my tummy. The feeling will get stronger and you will know that is the kick at around wk22. Don’t scare yourself.
Don’t worry! If you feel slight “bubbles popping” or fluttering kicks, it is all movements by the babies
