Week 28 Baby Movements

Hi mummies, I just entered 3rd trimester, currently week 28. I have a pulling pain on my lower right abdomen this morning till evening. And generally, my baby seems to move quite minimally (maybe just not an active baby?). Wondering if it is normal for minimal movement? Anyone has such experience of baby not very active but is still healthy at birth? Had a miscarriage before, hence a bit worried. Thanks!
