Good day co-mommies, nag start ko maramdaman si baby at 18 weeks naranasan ko ung 'quickening'

naninigas din sya minsan at nararamdamn ko sya ng ilang araw, pero nag less sya and madalang sya ngayon 19th week ko, is this normal? i have no other symptoms like Pagduruga or pananakit ng puson. its just feel like ang tahimik nya.
