Is It Normal to Feel Cramps at 8 Weeks Pregnant?

Hi, Im 8weeks pregnant based on the app i use. i took PT twice and it came positive. pero hnd pa ako nagpapacheck up kasi balak namin sa monday aftr holy week nalang magpacheck up... last week i felt nausea fatigue and vomiting. uminom ako ng kremil-s kala ko kasi hyperacidity lang then i decided to took the PT nga and positive nga. now i feel better but medjo may cramps ang belly ko pag gutom or pagod, pag 8 weeks ba ma-feel na ang pag galaw ng baby? it seems like im not preggy hehe..
