How does fetal kicks feel?

As in parang may pumitik ng once sa my bandang puson po. At first mapapa isip ka pa kung c baby na ba yun. Pero kapag madalas mo na sya maramdaman madidistinguish mo na sya na talaga yun. Biglang pitik lang talaga. Nag start ko sya ma feel on my 16th week, currently 17 weeks and 4days, mas madalas ko na maramdaman though may mga days na madalang lang and meron naman na madalas. Posterior placenta daw kasi kaya mas maaga ko naramdaman fetal kicks, or quickening.
