Oo normal yan, pero depende talaga sa bawat mama, some of us feel it agad, some later pa! At 6 weeks, ang uterus mo ay lumalaki na, kaya mararamdaman mo na siya, lalo na kung second pregnancy mo or third na. Pero to be on the safe side, it's best to mention it sa OB mo during your first visit para ma-check lang nila if everything's good, lalo na kung may sakit or unusual feelings ka pa.
