Baby movements???

Hi, mommies! First pregnancy ko and 28 weeks now. I'm just curious about my baby's movements. There are times na magkukulit sya at hihimasin ko ung tyan ko.. everytime na himasin ko kung san ako naghimas na part mejo parang maninigas... ung part lang na un... halata s tyan dahil hindi pantay ung shape.. is it possible na ulo un ni baby or other part ng katawan? Ty in advance~~~ ?
