Ay mama, please check with your OB right away, ha? Reduced movements kahit paano ay kailangan i-monitor closely, lalo na at ganitong stage na. Hindi ko dapat mag-assume, pero better safe than sorry talaga, go to your clinic or labor and delivery para ma-assess properly.
One of my mum friends nag-worry din about this, and her doctor did a monitoring session agad. It gave her peace of mind, and that's what matters, 'no? Prayers for you and baby.
