heard heartbeat two days ago but still don't feel kicks

AG
I don't have placenta pervia or anterior placenta. This is my 28th week (28+3). I felt few kicks and turns some days ago and went in for a routine visit two days ago. Everything looked fine. Now after I started officially recording kicks and swirls, I don't feel him move as much. I see hiccups when I drink tea but that's it. Is there something to worry? Not sure what doctor would say- I literally met her two days ago. Will call her nevertheless but would like to hear from you moms too. I am a first time mom btw.
