Baby movement? ~22wks

I am 21 weeks and 2 days. I've felt things but am not sure it was the baby. The ultrasound tech said based on the placement of my placenta I will feel later, but most feel I should by 22 weeks (not far off). This is my first. Anyone else experiencing this? Can anyone tell me where in your abdomen you feel the kicks and what it feels like? None of the online info says where you feel it. Many thanks!!
