Ay oo, very common yan sa 8-9 months po! Those little twitches and spasms are usually just baby hiccups or muscle movements, super normal at walang dapat alalahanin, kaya ng karamihan sa bumubuntis. A few of my mum friends said nararamdaman nila ito lalo na pag gabi or when baby's active, so you're definitely not alone! That said, kung parang unusual na intense or nag-alala ka talaga, better to mention it to your OB during your next checkup para peace of mind lang.
